Question 1

A 25.00-mL sample of H2SO4 is titrated with 0.2453 M NaOH. The titration requires 32.47 mL of NaOH solution to neutralize the H2SO4. What is the molarity of the H2SO4?

◦ 0.3186 M
◦ 0.1889 M
◦ 0.3777 M
◦ 3.309 M
◦ 0.1593 M

Question 2

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 2.90 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)

◦ 34.0% Sn
◦ 0.956% Sn
◦ 96.7% Sn
◦ 66.0% Sn
◦ 1.98% Sn
