A copper rod with a mass of 21.0 g cools from 95.0oC to 45.0oC when placed in a water bath. If the initial temperature of the water bath is 28.0 oC, what is the mass of water present in the water bath? The specific heat capacities of water and copper are 4.18 J/g oC and 0.385 J/g oC respectively. Assume that no heat is dissipated to the surroundings.
