The specified heat capacity of silver is 0.24 J/C.g. Please help with this Ap chem quastion.?

Question

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

Answer 1

Heat energy= mass*specificheatcapacity*(Tf-Ti)

Can you take if from here?

Answer 2

I gave the information to work all of these. Surely you can plug in the numbers.
