I need to find how many Oxygen atoms are in 1 gram of Al2(SO4)3. I have tried finding the mass percent, and working it from there, but I can't get the right answer. Does anyone know how to solve this?

Mole contain (6.02 x10 to the power 23) of molecules
1 gm /molecular weight of Al2(SO4) = no. of moles in one g
molecular weight of O2/molecular weight of the sulphate x100= percent of oxgen in one mole,
then calculate the percent of oxgen in the moles in 1 g
the result multiplied by 6.02 x 10 to the power 23 gives the no.of oxgen in 1 g of sulphate and then the numbers of atoms of Oxygen.

First find the number of moles(x) = weight(1g)/(molecular weight)
so there are x moles or Avagadro's constant*x molecules of the Al compound. As there are 12 O atoms the answer is 12 times this value.

find the molecular weight of aluminium sulphate
192/molecular weght of aluminium sulphate will give the weight of oxygen in 1 gm of aluminium sulphate
first of all find the weight of oxygen in 1 gram of Al2(SO4)3
in 32 gms of oxygen there are 6.022*10^23 molecules
so weight of oxygen multiplied by 6.022*10^23 will give the no of molecules
no of atoms=twice the no of molecules because oxygen is diatomic
