I assume you mean the 'specific' heat capacity its units are J/kg/K so take the value for Joules, and divide by mass in kg, then divide that by temperature change in K (Be sure to convert mass to kg) Then check your answer against table to make sure it is 'sensible' (it does not need ot be identical to the given value - but it should be in the same order...) (IF for some reason it does not mean 'specific' heat capacity, then do not divide by mass. Units are J/K)'
