1. The problem statement, all variables and given/known data I have done an experiment in which I measured the specific heat capacity of a coin. I would like to compare the results to the actual value. I have found out that the coin is made of Cupronickel alloy (for simplicity let's assume it's just 75% copper and 25% nickel). SHC of copper: 0.39 kJ/kg K SHC of nickel: 0.54 kJ/kg K Knowing the SHC values of the two elements (copper and nickel) how would I go about calculating the theoretical value of the SHC of the Cupronickel alloy, so that I can compare it to my experiment's results?
