heat capacity

[dg_5021]

When using a different calorimeter, and mixing 50 ml of hot water at 65 C with 60 ml of water in the calorimeter at 25 C, the temperture of the calorimeter increased by 5.5 C. Calculate the heat capacity of this calorimeter. Is this a better or worse calorimeter than the one used in the sample calculations?

This problem gets me all confused? Is there a formula that would make it easier? please help

As with all problems, if they ask for X. The first thing you want to ask yourself is, what is the definition of X? In this case heat capacity.
