Enthalpy help?

I need help working out enthalpy change.

25 cm^3 of Copper sulfate reacts with 6 grams of Zinc (excess) to determine the enthalpy change for a displacement reaction.

The change in temperature was 54 C, specific heat capacity : 4.18

Calculate the Enthalpy change.

Calculate the Enthalpy change for one mole of Zn and CuSO4(aq).

I missed out on some recent classes, so I'm pretty clueless as to how I'm suppose to do this. Thanks

uhh idk if i remember this but i think it was:
-Q/n=delta H, n being the number of moles
Q=mc delta t
m being the mass, c being the specific heat capacity, and delta t being the change in temperature
