In the laboratory a student uses a "coffee cup" calorimeter to determine the specific heat of a metal.

She heats $19\mathrm{.}7$ grams of lead to $98\mathrm{.}87C$ and then drops it into a cup containing $76\mathrm{.}3$ grams of water at $23\mathrm{.}73C.$ She measures the final temperature to be $24\mathrm{.}49C.$ Assuming that all of the heat is transferred to the water, she calculates the specific heat of lead to be $,\frac{J}{g}C.$
