Question

if 0.582 moles of zinc reacts with excess lead(IV) sulfate how many grams are zinc sulfate would be produced?

Answer 1

Chemical reaction is:
Zn+PbSO4→ZnSO4+Pb
From the balanced equation 2 moles of Zn make 2 moles of ZnSO4 

You have 0.534 moles of zinc so you make 0.534 moles of ZnSO4. 
Molar mass of ZnSO4 = 161 g/mol
mass = no of moles * molar mass
mass = 0.534 * 161
mass = 85.974 g
