The specific heat capacity of silver is 0.24 J/°C·g.
(a) Calculate the energy required to raise the temperature of 140.0 g Ag from 273 K to 295 K.
J
(b) Calculate the energy required to raise the temperature of 1.0 mol Ag by 1.0°C (called the molar heat capacity of silver).
J/mol°C

a)
q = mass Ag x specific heat Ag x (Tf  Ti)
You have mass Ag, sp. H. Ag, and Tf (final T) and Ti (initial T). Solve for q.
b)
You have specific heat Ag which is the energy required to raise 1 g Ag by 1 degree C.
0.24 J/g*c x (107.87 g Ag/mol) = ?? 
to find C am i just using the equation from a?

You didn't post a c part.

I will be happy to critique your work.
a. energy= mass*c*deltaTemp
b. energy/mole= energy/gram*grams/mole 
i don't understand b.

You have specific heat in J/g. So you multiply the molar mass to obtain J/mol.
