An unknown metal of mass 0.280 kg is heated to 160.0°C and dropped in an aluminum calorimeter of mass 0.250 kg that contains 0.170 kg of water at 30°C. The calorimeter, water, and unknown metal have a final temperature of 46.0°C. Find the specific heat of the unknown metal. Hint: you need the specific heat of water and aluminum. Use units of [J/(kg.K)] and the values in your book for the specific heat.
