I used the formula and came with two answers

100.32 joules and 10.01 joules.

Which is correct?

q = mass x specific heat x delta T.

5016 = 5.00 x 10^2 x Cp x 10

5016 = 5.00 x 10^3 Cp

Cp = 5016/5.00x10^3 = 1.003 J/g*C (You didn't put units on your answer, a No, No.)

I can understand how you might get a power of 10 off but I don't understand how you can get two answers. You will need to round the answer to the correct number of significant figures.
