2H3PO4 + 3Na2SO4 → 2Na3PO4 + 3H2SO4

Molar masses:

Sodium sulfate = 142.05 g/mol

Phosphoric acid = 98 g/mol

Sodium phosphate = 163.94 g/mol

Sulfuric acid = 98.09 g/mol

a) If 1.08 g of sodium sulfate reacts with an excess of phosphoric acid, how much sulfuric acid is produced?

b) If 0.726 g of sulfuric acid is produced in the laboratory experiment, what is the percent yield of sulfuric acid?
