A 62.5 mL sample of a 0.106 M potassium sulfate solution mixed with 39.0 mL of a 0.122 M lead(II) acetate solution and the following precipitation reaction occurs: K₂SO4 (aq) + Pb(C₂H₂O₂)2 (aq)-2KC₂H₂O₂ (aq) + PbSO4(s) The solid PbSO4 is collected, dried, and found to have a mass of 1.01 g. Part A Identify the limiting reactant. Pb(C₂H₂O₂)2 OK₂SO4 OKC₂H₂O₂ OPbSO4 Submit Previous Answers ✓ Correct The limiting reactant of a reaction is found by calculating the number of moles of each reactant and comparing them. The reactant with the least number of moles is considered the limiting reactant because once all of it has reacted the reaction stops despite the presenc of another reactant. The limiting reactant is important when determining the theoretical yield of a product. Part B Determine the theoretical yield. mass of PbSO4 = Submit Part C [5] ΑΣΦ Request Answer Determine the percent yield. IVE] ΑΣΦ ↑ → C G] ? [QC]] ? 8
