![49. [Algoríthmíc] A 3.00-g sample of an alloy (containing only Pb and Sn) was dissolved in
nitric acid (HNO,). 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 PbSO = 303.3 g/mol)
a) 33.3% Sn
b) 17.7% Sn
c) 50.0% Sn
d) 66.7% Sn
