You are given a crushed sample that is a mixture of limestone (CaCo3), lime (CaO), and sand. The calcium carbonate, limestone, is the only material present in the material that will decompose when heated. You subject a 5.3563g sample of the mixture to strong heating and after the sample reaches constant mass the sample has a final weight of 3.2887g. What is the percentage of calcium carbonate present in the original mixture? (f.w.t. CaCO3=100.1)
