Answer to Question #55667 in General Chemistry for rachel
When 60.8 g of calcium is reacted with nitrogen gas, 28.7 g of calcium nitride is produced.
What is the percent yield of calcium nitride for this reaction?
Express your answer with the appropriate units.
Percent yield = actual yield / theoretical yield * 100% Theoretical yield (Ca3N2) = n (Ca3N2) * M (Ca3N2) = m (Ca) / M (Ca) * 3 * M (Ca3N2) = 60, 8 g / 40 g/mol / 3 * 148 g / mol = 75 g Percent yield (Ca3N2) = 28,7 g / 75 g * 100% = 38,3 %.
