How many grams is 1 a.m.u. ? (please provide or show a Detailed SOLutioN) Thanks!
An atomic mass unit is equal to 1.66053892 × 10^-27 kilograms

@thomaster so, how do you compute for the grams?
What do you mean? what 1 amu is in gram? That's \(\large\sf 1.66053892 × 10^{-24}\) gram
@thomaster what is 1 amu in gram? --- this is what i meant now, how did you get 1.66 x 10^-24 gram? i need the solution too. if you may
It is just a constant, you can't calculate it. A long time ago they decided to take the mass of carbon-12 and divide that by 12 to get 1 amu.
@thomaster but how come my book has a derivation / solution of how to know how much is 1g in amu? see the attached picture below:
that's the relationship between the amu mass and avogadro's number Avogadro's number is the amount of particles in 1 mole of a compound. Like it says in your book, 1 gram is avogadro's number in amu You could solve this with a crosstable |dw:1372679331655:dw|
ok. i got it thanks @thomaster
@thomaster wait a minute. i'm mixed up how's you get 1.66x10^-24? when we're supposed to find how many grams is in 1 amu?
@thomaster if the answer is 1.66x10^-24; then how did you get 1.66x10^-24 as your solution variable?
1 divided by avogadro's number = 1.66*10^-24
because 6.022*10^23 amu = 1 gram
@thomaster where did 1 come from?
what's the precise formula?
what's the precise formula? and the summary of all? @thomaster
It's explained here: |dw:1372682633203:dw|
since 1*1 = 1 that's where the 1 comes from
ok thanks again for clarifying :))))))
