Thanks can you check one more

If it takes 105 calories to warm 100g of aluminium from 20oC to 25oC, what is the specific heat of aluminium?

Q = MxdeltaTxC

105cal = 100gx (5oC) x C

C = .21 cal/gCo

we get points off if we do not show our work and just give the answer

The number looks good to me. I suggest you write it as 0.21 cal/g*C. It's good practice to place a 0 before the decimal; sometimes people tend to overlook the decimal, especially if their eye sight is failing.
