Re: Stoichiometry...

Alright, here it is...

30 mol NH3; 17g/mol NH3; so you have 30 x 17 = 510g NH3

According to your equation, 17.4g (or 1 mol) of NH3 produces 1 mol Ammonium Sulfate. And 1 mol Al. Sulfate is 132g. Thus...

510g NH3 x 1 mol (NH4)2 SO4......x 132g (NH4)2 SO4
..................17.4g NH3..................1 mol (NH4)2 SO4....So 30 mol NH3 made 3869 g of (NH4)2 SO4

But you need moles, so 3869/132 will give you 7.6 mol

Hope this helps!
