q=mCT vs q=cT

How do you know which one to use?/what is the difference? For example, in winter 2015 final 1B you use q=mCT but in 1D you use q=cT.

You use q=mCT when finding the heat of a particular substance with a mass, change in temp, and specific heat capacity. However when solving a problem with a bomb calorimeter, the mass is not necessary to solve for a value. A more specific notation would be q(calorimeter) = C(calorimeter)T
