calculate the specific heat of a metallic element if 314 joules of energy are needed to raise the teperature of a 50.0g sample from 25C to 50C.

i'm not sure if you use the Q=(s)(m)(delta t) equation or not since it asks for the specific heat not the specific heat capacity.. i don't know if theres a difference or not...

1. specific heat is a shortened version of specific heat capacity.
Use 1 = mass x specific heat x delta T.

2. are the joules supposed to be on the side where the 1 is?

so its 314= 50x specific heatx 25?

3. Sorry, I made a typo. That should have read
q = mass x specific heat x delta T. I hit the 1 instead of q.
Yes, 314 = 50 x sp.h. x 25. Solve for sp.h.
