I'm not sure if this question would go under this topic but how come the question uses the formula q=CdealtT? I thought that the equation is q=mCdeltaT?

[Cynthia Tsang]

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

[Lisa Tang 1C]

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.

[soniatripathy]

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?

[Pooja Nair 1C]

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

[Juanalv326]

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