Given the following equation: Heat (cal) = g x ?T(°C) x specific heat and that the heat of water is 1.00 cal/g°C.

A metal object with a mass of 32 g is heated to 99°C, and then transferred to a calorimeter containing 75 g of water at 18°C. The water and metal object reach a final temperature of 24°C. What is the specific heat of this metal object?
