Question 1

Determine the theoretical yield and the percent yield if 21.8 g of K2CO3 is produced from reacting 27.9 g KO2 with 29.0 L of CO2 (at STP). The molar mass of KO2 is 71.10 g mol-1 and K2CO3 is 138.21 g mol-1.

4KO2(s) + 2CO2(g) → 2K2CO3(s) + 3O2(g)

◦ 179 g, 12.2% yield
◦ 27.1 g, 80.4% yield
◦ 91.7 g, 23.8% yield
◦ 61.0 g, 35.7% yield
◦ 206 g, 10.6% yield

Question 2

Determine the volume of SO2 (at STP) formed from the reaction of 96.7 g of FeS2 and 55.0 L of O2 (at 398 K and 1.20 bar). The molar mass of FeS2 is 119.99 g mol-1.

4FeS2(s) + 11O2(g) → 2Fe2O3(s) + 8SO2(g)

◦ 27.6 L
◦ 18.1 L
◦ 36.1 L
◦ 32.5 L
◦ 45.3 L
