How to calculate the heat gained by the calorimeter

Question

How to calculate the heat gained by the calorimeter, given, initial mass of calorimeter=40.32g, initial temp° = 31°c, temp° of hot water= 62°c, final temp° after mixture =54°c, final mass= 94.62g, mass of water= 54.30g heat lost by hot water= -1,824,480J

Answer 1

There's some extraneous info in the question. The heat lost by the water is equal to the heat gained by the calorimeter. (The calorimeter itself doesn't change mass). There's no calculation as far as I can see.

1,824,480J .
