calculate the specific heat for 18.5g sample of tin that absorbs 183 J when its temp increases from 35.0 degrees celcius to 78.6 degress celcius. I don't know where to even start, help?

Note the correct spelling of celsius.
q = mass Sn x specific heat x (TfinalTinitial)
183 = 18.5g x sp.h. x (78.635.0)
Solve for sph.
