Answer
a. 1.10x10^{3} g P4O6
b. 1.55x10^{3} g Ca3(PO4)2
c. 7.10x10^{2} g Na2HPO4
Work Step by Step
Simple Stoichiometry
a. P4O6
MW: 218.89 g/mol
mass of P4O6 = 5.00 mol P4O6 x (219.89g/mol P4O6) = 1.10x10^{3} g P4O6 (3 significant figures)
b. Ca3(PO4)2
MW: 310.179524 g/mol
mass of Ca3(PO4)2 = 5.00 mol Ca3(PO4)2 x (310.179524 g/mol Ca3(PO4)2) = 1.55x10^{3} g Ca3(PO4)2 (3 significant figures)
c. Na2HPO4
MW: 141.9573006 g/mol
mass of Na2HPO4 = 5,00 mol Na2HPO4 x (141.9573006 g/mol Na2HPO4) = 7.10x10^{2} (3 significant figures)
