i hope this helps you out i have other chemistry stuff up too so have a look
the avagadro constant is the number of molecules or atoms in a mole of a substance this is a constant figure which is 6.02*10 to the power of 23 it is the number of atoms in 12g of carbon 12
you can use this figure to work out the number of atoms in a given mass of a substance for example
6g of C would have half the number of atoms in as 12g ( which is the same as the atomic number and the number of grams in a mole) so the answer is 3.01*10 23
you can use the advogadro constant and divide by the ram to tell you the number of atoms in a molecule and scale up by the number of grams you have
but how does this work with diatoms ?
you just use the RMM so for O2 you use 32 but make sure to look whether they want the number of…
