4C.3

Hi, 4C.3 says "Calculate the final temperature and the change in enthalpy when 765 J of energy is transferred as heat to 0.820 mol Kr(g) at 298 K and 1.00 atm (a) at constant pressure; (b) at constant vol- ume. Treat the gas as ideal."
I get how you have q and you have separate equations for each a and b, however i still don't understand to calculate the final temperature?

they give you the value for q, you can find Cv and Cp from the ideal gas heat capacity eqn, and you're given Ti, so you're just solving for Tf.
