(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).

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) = ??
