Question: A 3.00-g sample of an alloy (containing only Pb and Sn) was dissolved in nitric acid(HNO3). Sulfuric acid was added to this solution, which precipitated 2.93 g of PbSO4. Assuming that all of the lead was precipitated, what is the percentage of Sn in the sample? (molar mass of PbSO4 = 303.3 g/mol)

[A] 50.0% Sn

[B] 66.7% Sn

[C] 2.00% Sn

[D] 17.7% Sn

[E] 33.3% Sn
