Unformatted text preview: the reaction was 93.7%, what is the theoretical yield of this reaction? Actual yield = 30.7 g Theoretical yield = ??? Percent yield = 93.7 Actual yield Theoretical yield Actual yield 30.7 g Theoretical yield = = = 32.8 g % yield 0.937 % yield = 5 13. How many grams o f SO2 can be produced from reaction of 10.0 g of H2S and 10.0 g of O2, as shown below: 2 H2S + 3 O2 ® 2 SO2 + 2 H2O Assume H2S is LR: 1 0.0 g H 2 S x 1 mol H 2 S 2 mol SO 2 x = 0.293 mol SO 2 34.1 g H 2 S 2 mol H 2 S Assume O2 is LR: 10.0 g O 2 x 1 mol O 2 2 mol SO 2 x = 0.208 mol SO 2 32.0 g O 2 3 m ol O 2 The second assumption is correct. Therefore, oxygen is the limiting reactant. 0.20 8 mol SO 2 x 64.1 g = 13.3 g SO 2 1 m o l 14. When 50.0 g of N2 is reacted with an excess of other reactants as shown below, 20.0 g of NaCN was produced. What is the percent yield of this react ion? Na2CO3 + 4 C + N2 ® 2 NaCN + 3 CO Calculate the theor...
