A piece of chromium metal with a mass of 24.26g is heated in boiling water to 98.3C and then dropped into a coffee-cup calorimeter containing 82.3g of water at 23.3C. When thermal equilibrium is reached, the final temperature is 25.6C. Calculate the specific heat capacity of chromium.

You determine that 187 J of heat is required to raise the temperature of 93.45g of silver from 18.5 to 27.0C. What is the specific heat capacity of solid silver?
