Explain caco3 in the original hydrated sample

Reference no: EM13502107

A sample is composed of a mixture of CaCO3 and CuSO4*5H2O. A chemist decided to analyze the mixture by dehydrating it by heating it to 120 degrees Celsius for 12 hours. If a 5.327 g sample weighed 4.281 g after dehydration, what is the percentage of CaCO3 in the original hydrated sample?
