q = C (delta T) is also an equation that works, although I'm not sure when each is applied.

The question asks for the heat capacity(C) of the calorimeter and not the specific heat capacity because specific heat capacity is for a certain mass of a sample, which we can't necessarily assign in this problem. The definition of heat capacity is heat supplied/change in temperature.

In equation form: C=q/delta T.

In equation form: C=q/delta T.

will the heat capacity of a calorimeter always be q=C(deltaT) or are there cases which will require us to take mass into consideration and use the specific heat capacity?

I don't think you factor in mass when you calculate the heat capacity of the calorimeter

Unless it specifically states to use mass, you can assume to use moles or just go ahead and use mcdeltaT, m meaning for mass
