The specified heat capacity of silver is 0.24 J/C.g. Please help with this Ap chem quastion.?
a. Calculate the energy required to raise the temperature of 150.0 g Ag from 273 K to 298.
b. Calculate the energy required to raise the temperature of 1.0 mol Ag by 1.0C (called the molar heat capacity of silver).
c. It takes 1.25 Kj of energy to heat a sample of pure silver from 12.0C to 15.2C. Calculate the mass of the sample of silver

All of these use
q = mass x specific heat x (TfialTinitial).
Substitute and solve for the unknown.
