Question

A piece of Copper alloy with a mass of 89.0 g is heated at 30.0 degrees C to 50.0 degrees C. In the process, it absorbs 517 J of energy as heat. What is the specific heat of this copper alloy?

and Please do a step by step, I really want to see where I keep going wrong.
If you had posted your work I would have seen where it was and if you were missing a concept. And it would have taken me much less time.
q = mass x specific heat x delta T.
517 = 89.0 x specific heat x 20
Sp. h. = ?
Answer is 0.290 J/g*C
