Explanation / Answer

Given

100 g of calcium carbonate gives 33 g of CO2

reaction is

CaCO3 ----> CaO + CO2

Data

molar mass of CaCO3 = 100 g/mol

molar mass of CO2 = 44 g/mol

Solution

100 g of CaCO3 will contain = 100 g / 100 g/mol = 1 mole of CaCO3

33 g of CO2 will contain = 33 g /44 g/mol = 0.75 mole of CO2

1 mole of CaCO3 is present which should theoretically yield 1 mole of CO2

whereas actual yield is 0.75 mole of CO2

percent yield = ( actual yield / theoretical yield ) * 100 % = (0.75/1) * 100 % = 75 %

Answer = 75 %
