The following data was collected by a student performing the determining the specific heat capacity and molar heat capacity of copper portion of the experiment.A 35.52g copper coil is removed from boiling water and is immediately immersed in a calorimeter with a constant of 63.2J/0C. The calorimeter contains 74.61g of water that is initially at 21.420C. The system reaches equilibrium at a temperature of 24.300C. What is the molar heat capacity of the copper?
