5.00g of an unknown solid was heated to 99.7 degrees C and placed in a calorimeter with 1.25L H20. The initial temp of the water was 25.0 degrees C. During the experiment, the temperature of the water rose to 63.5 degrees C. what is the specific heat of the sample? Do you think the solid is a metal or nonmetal?

Heat lost by solid + heat gained by H2O = 0

[mass solid x specific heat solid x (Tfinal-Tinitial)] + [mass H2O x specific heat H2O x (Tfinal-Tinitial)] = 0
Solve for specific heat solid.
