What is the percent yield of the following reaction if 60 grams of CaC

1.	What is the percent yield of the following reaction if 60 grams of CaCO3 is heated to give 15 grams of CaO? CaCO3→CaO + CO2
Answer» The percent YIELD is 45 %. CaCO₃ →CaO + CO₂ First, calculate the theoretical yield of CaO. Theor. yield = 60 g CaCO 3 × 1 MOL CaCO 3 100.0 g CaCO 3 × 1 mol CaO 1 mol CaCO 3 × 56.08 g CaO 1 mol CaO = 33.6 g CaO Now calculate the percent yield. % yield = actual yield theoretical yield × 100 % = 15 g 33.6 g × 100 % = 45 %

Answer»

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

theoretical yield

100

15 g

33.6 g

100
