A 170.0 g sample of metal at 79.00*C is added to 170.0 g of H2O(l) at 14.00*C in an insulated container. The temperature rises to 16.19*C. Neglecting the heat capacity of the container, what is the specific heat of the metal? The specific heat of H2O(l) is 4.18J/(g x *C). Please show the formula used and detailed work on how to solve this.
