4 HgS + 4 CaO -> 4 Hg + 3CaS + CaSO4 You began this reaction with 21.4 grams of calcium oxide. If you actually produced 9.35 grams of calcium sulfate, what was your percent yield, rounded to 3 sig-figs.
Use the following molar masses for your calculations:
Hg= 200.59 g/mol
S= 32.066 g/mol
Ca= 40.078 g/mol
O= 16 g/mol
