Hi I have a quick question:

My kaplan book and my kaplan instructor says that q = m (Delta Heat of fusion)

, but

when I watch chad videos he says that q = n (Delta Heat of fusion)

Does anyone know which is the correct formula I should go with when solving calorimetry problems?

Thank you!!

q=delta heat of fusion times mass, just like q=mcdeltaT

The one that you choose depends on what unit is given for Heat of fusion. Whatever it is, they gotta cancel so unit of q is J or kJ. m can be calculated from n and vice versa.
