If 50.8 grams of calcium carbonate are decomposed what is the theoretical yield of carbon dioxide

The percent yield is 45 %.

CaCO₃ →CaO + CO₂

First, calculate the theoretical yield of CaO.

Theor. yield =

60 g CaCO

1 mol CaCO

100.0 g CaCO

1 mol CaO

1 mol CaCO

56.08 g CaO

1 mol CaO

=

33.6 g CaO

Now calculate the percent yield.

% yield =

actual yield
