Part 4Homework Answers
according to balanced reaction
12 g C reacts with 143.1 g Cu2O
11.5 g C reacts with 11.5 x 143.1 / 12 = 137.14 g Cu2O
but we have 114.5 g Cu2O
so Cu2O is limiting reagent.
143.1 gCu2O forms 2 x 63.55 g
114.5 g Cu2O forms 114.5 x 2 x 63.55 / 143.1 = 101.7 g Cu
therotical yield = 101.7 g
actual yield = 87.4 g
% yield = (87.4 / 101.7) x 100
% yield = 85.94
