◦ 55.34 mL
◦ 11.07 mL
◦ 16.14 mL
◦ 32.29 mL
◦ 47.10 mL

Question 2

When 20.0 mL of a 0.250 M (NH4)2S solution is added to 150.0 mL of a solution of Cu(NO3)2, a CuS precipitate forms.  The precipitate is then filtered from the solution, dried, and weighed.  If the recovered CuS is found to have a mass of 0.3491 g, what was the concentration of copper ions in the original Cu(NO3)2 solution?
◦ 3.65 × 10–3 M
◦ 1.22 × 10–2 M
