Question 6: A 55.0 mL sample of a 0.102 M potassium sulfate solution is mixed with 35.0 mL of a 0.114 M lead(lI) acetate solution and this precipitation reaction occurs: K,so,(aq) + Pb(C2H,O2)2(aq) â 2 KCMo, (aq) + PbSO4 (s) The solid PbSO, is collected and dried, and found to have a mass of 1.01 g. Determine the limiting reactant, the theoretical yield and the percent yield. (answer: Pb(C,H,02)2, 1.21g, 83.5%)
