Determine the heat capacity Cp and the molar heat capacity Cp,m of a solid sample from the observation that transferring the sample with n = 4.55 mol from boiling water (at constant ambient pressure) into 185.0 g of water initially at 25.1ºC raised the water temperature to 63.2ºC. Assumethat no heat is lost to the environment and that water has a constant molar heat capacity of Cp,m = 75.3 J K^?1 mol ^?1 in the 20ºC to 100ºC range.
