Las unidades de masa atómica (u) se define como 1/12 de la masa del isótopo C12.
La masa molecular relativa es un número que indica cuántas veces mayor es la masa de una molécula de una sustancia con respecto a la unidad de masa atómica. Su unidad es el Dalton o unidad de masa atómica, que se abrevia u (antes uma).
La masa molecular se determina sumando las masas atómicas relativas de los elementos cuyos átomos constituyen una molécula de dicha sustancia. A pesar de que se sigue diciendo popularmente peso molecular, el término correcto es masa molecular. La masa molar de una sustancia coincide numéricamente con la masa molecular, aunque son cosas distintas.
Por ejemplo: la masa molecular del H2O será:
1,00794 x 2 + 15,9994 = 18,015128 u
(masa atómica del H: 1,00797, masa atómica del O: 15,9994)La masa molar (símbolo M) de un átomo o una molécula es la masa de un mol de dicha partícula expresada en gramos. Es una propiedad física característica de cada sustancia pura. Sus unidades en química son los gramos por mol (g/mol).
Podríamos decir que la masa molar es lo mismo que la masa molecular pero en vez de estar en unidad de masa atómica (u) está en gramos/mol.
Podríamos decir que la masa molar es lo mismo que la masa molecular pero en vez de estar en unidad de masa atómica (u) está en gramos/mol.
masa molar de H = 1 g x 2 átomos = 2
masa molar de 0 = 16 g 1 átomo = 16
Total = 18 g /mol.
La cantidad correspondiente a 1 mol es 6,022 x 10 elevado 23 (nº o constante de Avogadro).

ResponderEliminar¿Y las definiciones de masas absolutas?
ResponderEliminarSe las metieron en el orto :v
EliminarPorque no te callas, y te vas a hacer algo más productivo que romper los huevos aca, la recalcada concha de tu hermana
EliminarPor que no te callas tu de una puta vez y te vas a tomar por culo?
EliminarHabla todo el articulo de masa atomica relativa solamente y de otra boludes que no me importa :v , me sirve para safar en clase. Gracias
ResponderEliminarI cum Blood
Eliminarjajajajajaja no
ResponderEliminarNo estuvo tan explicado pero ke salvo de la tarea GRASIAS!!
ResponderEliminarno maches cabron >:v me pase busacando las masas absolutas aunque me sirvio lo otro.... gracias
ResponderEliminarPOSDATA: la profe me saco un 100
hola cuales son las diferencias entre masa atómica absoluta y masa atómica relativa???
ResponderEliminarHola y las absolutas
ResponderEliminarSwollen with liquid
ResponderEliminarReady to burst
A load of my lymph
Will quench this dead body's thirst
One month in the grave
twisted and half decayed
She turned a putrid yellow
I pissed in her maggot filled asshole
Fucking the rotting
My semen is bleeding
The smell of decay
Seeps from her genital cavity
The smell was unbearable
As I unburied her
I cum blood from my erection
I feel it run
down her throat, swallow
Eyes glassy and vacant
body dug up to play with
Skin greasy and naked
tounguing her rotted anus
I need a live woman
to fill with my fluid
A delicate girl, to mutilate, fuck and kill
her body exceptional
she thought I was normal
but I wanted more
I came blood inside of her
chocking on the clot
gagging on the snot
gushing blood, from her mouth
bloody gel leaking out
Body buried in a shallow grave
Unmarked for none to find
The sickness I have left behind
Undetected go my crimes
The greatest thrill of my life
To slit my own cock with a knife
Violent, climax
Serging serum
on my skin
Back from the dead
I am resurrected
to spew, putrefaction
EliminarI was once a man before I transformed
into this molester, freshly deceased children
You have born, torn by my rape
The dead are not safe, the lifeless child corpse
I will violate
Pleasure from the dead, complete satisfaction
I open the coffin
Sick thoughts run through my head as I stare
At the dead, over and over, I can't escape
I begin the dead sex, licking her young, rotted orifice
I cum in her cold cunt, shivering with ecstasy
for nine days straight I do the same
She becomes by dead, decayed child sex slave
her neck I hack, cutting through the back
I use her mouth to eject
Here I cum, blood gushes from
bleeding black blood
her head disconnected
As I came, viciously I cut, through her jugular vein
She's already dead, I masturbate with her severed head
My lubrication, her decomposition
Spending my life molesting dead children
Intercourse with infants
Curing heads on top of spikes
boiling skulls
Skin sliding off of bones
Voices
The voices call
Voices
The voices are calling me
Buried dead I've spiritually infected
Call to me from beyond their graves
Bleed
I now bleed pus
I bleed, the blood of the dead
I bleed on her livid skin
Thrusting myself within
Beginning to chop through her hairless crotch
Beyond what we know as death
It haunts me everyday
I hear the voice of every child
That lies next to me decayed
A fresh corpse, to fill with my infection
Tortured before death, no orifice left unfilled
Violated after death
Virgin hole I infest
Anal pore spewing cess
The sacred juice I injest
Your dead child I defile
Necropedophile
EliminarThere's something inside me
It's, it's coming out
I feel like killing you
Let loose of the anger, held back too long
My blood runs cold
Through my anatomy, dwells another being
Rooted in my cortex, a servant to its bidding
Brutality now becomes my appetite
Violence is now a way of life
The sledge's my tool to torture
As it pounds down on your forehead
Eyes bulging from their sockets
With every swing of my mallet
I smash your fucking head in, until brains seep in
through the cracks, blood does leak
distorted beauty, catastrophe
Steaming slop, splattered all over me
Lifeless body, slouching dead
Lecherous abcess, where you once had a head
Avoiding the prophecy of my new found lust
You will never live again, soon your life will end
I'll see you die at my feet, eternally I smash your face
facial bones collapse as I crack your skull in half
Crushing, cranial, contents
Draining the snot, I rip out the eyes
Squeezing them in my hands nerves are incised
Peeling the flesh off the bottom of my weapon
Involuntarily pulpifying facial regions
Suffer, and then you die
Torture, pulverized
At one with my sixth sense, I feel free
To kill as I please, no one can stop me
Created to kill, the carnage continues
Violently reshaping human facial tissue
Brutality becomes my appetite
Violence is now a way of life
The sledge's my tool to torture
As it pounds down on your forehead
Alive alone now that they've gone dead but unburied
EliminarI've seen it unfold, terrible scenes of agony
Eyes in the darkness
Echoing their madness
The sights that have passed before them
Watching as though it has never happened
Now I only listen to what is not spoken
Murder, hatred
Anger, Savage
Killings I have caused
more than can be counted
orgies of sadism
And sexual perversion
Virgin
Tied to my mattress
Legs spread wide
Ruptured bowel, yanked
From her insides
Devirginized with my knife
Internally bleeding
Vagina, secreting
her blood-wet pussy
I am eating
on her guts I am feeding
Mutilated with a machete
I fucked her dead body
The first and last
Your life's only romance
My knife's jammed in your ass
As you die you orgasm
Pass on to the dead
Nerve trembling convulsions
No longer looking human
I never see them, but I know they're there
Locked in my subconcious
Obscene memories I thought I'd forgotten
Haunting unrealities
Tear at me
Hold her arms
Her mouth taped shut
Screams unheard
Out pour her guts
Layers of flesh peeling away
Languish in your own decay
descriptions of my killings
bone chilling
Terror, tear, her
Virgin cunt
Virgins are my victims
Their tight interiors I explore
Sharpened utensils of torture
Now inserted inside of her
Sex organs extracted for eating
On her liver I am gnawing
Forbidden lust for guts
Ripped from her cunt
Tears of blood cry down her thigh
I ram my fist inside her hole
From her crotch piss now flows
Rectum filled with shit
I fucked her emptied body
Until she became stiff
Hey, Jude, don't make it bad
EliminarTake a sad song and make it better
Remember to let her into your heart
Then you can start to make it better
Hey, Jude, don't be afraid
You were made to go out and get her
The minute you let her under your skin
Then you begin to make it better
And anytime you feel the pain,
Hey, Jude, refrain
Don't carry the world upon your shoulders
For well you know that it's a fool
Who plays it cool
By making his world a little colder
Nah, nah nah, nah nah, nah nah, nah nah
Hey, Jude, don't let me down
You have found her, now go and get her
Remember to let her into your heart
Then you can start to make it better
So let it out and let it in,
Hey, Jude, begin
You're waiting for someone to perform with
And don't you know that it's just you,
Hey, Jude, you'll do
The movement you need is on your shoulder
Nah, nah nah, nah nah, nah nah, nah nah yeah
Hey, Jude, don't make it bad
Take a sad song and make it better
Remember to let her under your skin
Then you'll begin to make it better, better, better, better, better... oh!
Nah, nah nah, nah nah, nah, nah, nah nah,
Hey, Jude
Nah, nah nah, nah nah, nah, nah, nah nah,
Hey, Jude
