Question
Calcium carbonate was reacted with hydrogen chloride. What is the percentage yield of carbon(iv)oxide produced if 3.65g of the gas is collected when 10g of calcium(iii)oxocarbonate reacts

First there is no such thing as calcium(iii) oxycarbonate. Ditto for calcium(iv) oxide.
CaCO3 + 2HCl ==> H2O + CO2 + CaCl2
mols CaCO3 = grams/molar mass = ?
Using the coefficients in the balanced equation, convert mols CaCO3 to mols CaO.
Convert mols CaO to grams CaO by grams = mols x molar mass = ?. This is the theoretical yield (TY). The actual yield (AY) given in the problem is 3.65.
%yield = (AY/TY)*100 = ?
