q = mass e.g. x specific heat e.g. x (Tfinal-Tinitial)
668= 26.7(2.42)(X-32.5) ?
If Tfinal is 32.5 and Tinitial is X, it appears you have reversed the numbers. I have
-668 = 26.7(2.42)(32.5-X)
However, you reversed the sign on Tfinal-Tinitial AND you used a + instead of a - sign for heat lost of -668 so the sign turns out ok as well as the number.
