In order to answer this question you need more information. Namely: the units that are given for the amount of heat absorbed - is it kJ, j, cal, or what? Also, you would be solving for the specific heat capacity of the substance (q = mc ΔT). To "identify" the substance from the list you must know the c values of the given choices to choose from.
