CaCO3 ---> CaO + CO2 n = m/Mm n = 5.0g /100g/mol n = 0.05mol of CaCO3 mole ratio CaCO3 : CO2 1: 1 0.05mol : x x = 0.05mol of CO2 V = n x Vm v = 0.05mol x 24mol /dm³ v = 1.2dm³ (b) % Yield = Actual yield/Theoretical yield x 100 % = 0.9/1.2 x 100 % = 75%

Sir is it always that when dealing with mole concept we have to use the balance equation

No unless the question involves finding the amount of products formed from the amount of reactant given. Actually there many different forms of question on mole concept which you need to master in order to under where balanced questions are used and where they are not used.
