Suppose we have a piece of a candy bar that has an initial mass of 28g.  If we ignite the piece of candy bar (literally burn it), and it increases the temperature of 285.23g of water from 18.95°C to 77.43°C, how many calories per gram of energy did the candy bar provide if the final mass of the marshmallow is 4.45?  Note: 1.00 cal = 4.184 J. Give your answer in units of cal/g.
