A calorimeter contains 250 g of water at 22.3 degrees Celsius. A block of metal with a mass of 85 g is heated to 97.9 degrees and then placed in the water in the calorimeter. After sufficient time, the temperature of the water is measured and found to be 27.4 degrees. Calculate the heat capacity per gram of metal. Assume no heat is lost to the calorimeter or the surroundings. The specific heat capacity for water is 4.184 J/g
