Question

If  of zinc reacts with excess lead(IV) sulfate, how many grams of zinc sulfate will be produced in the reaction?

Answer 1

Pb(SO₄)₂ + 2 Zn ==> 2 ZnSO₄ + Pb ... balanced equation

Using the stoichiometry of the balanced equation and dimensional analysis...

0.431 mol Zn x 2 mol ZnSO₄/2 mol Zn x 161.4 g ZnSO₄/mol ZnSO₄ = grams ZnSO₄ (do the math)
