Hey Guys am not sure if l'am thinking of something else when calculating ions in a compound but if l am can someone point me in the right direction please
3.42g of Al2(SO4)3
I did M/GFM got 0.01 mol then 0.01* 6.02*10^23= 6.02*10^21 ions

Am l thinking of something else entirely?

You've found the number of molecules. But the compound is made up of Aluminium and sulfate ions, so one molecule = 2+3=5 ions, so you need to multiply the number of molecules by 5 to get the number of ions.
