You are given a mixture of CuCO3 and CuO. You place the mixture in a crucible and heat it to decompose the CuCO3 into CO2 gas and CuO. You made sure that the CuCO3 had completely decomposed by constantly heating it, cooling it, and weighing it until the mass remains the same. Using the data below from the experiment, calculate the % CuCO3 in the original sample.
