Question

How many moles of oxygen atoms in 1 mole of aluminium sulphate?

Answer 1

one mole of aluminium contains some amount of aluminium sulphur and oxygen..
this the mass of oxygen in one mile of aluminium sulphate = 4 × 16 grams
= 64 grams

this number of moles =
mass given / atomic mass

64/16 = 4 moles

Answer 2

aluminum sulphate = Al2(SO4)3
moleculer mass =2 x 26+(32+64)3
                          52+288=340 u
so 340=I mole
we have moleculer mass of oxygen in Al2(sO4)3=64
I mole of oxygen =16 gram
1/16 mole of oxygen = 1 gram
1/16x64 mole =64 gram
4 moles= 64 gram
