Please any help would be much appreciated!!!

A pair of students performed an experiemnt to determine the heat of formation of zinc oxide. The reactions are entirely analogous to the reactions of magnesium oxide. They reacted 1.504 g of zinc with 100.20 g of 0.50 M hydrocholoric acid. (Zinc is the limiting reagent.) The initial temperature was 23.11 C and the final temperature was 31.36 C. If the heat capacity of zince chloride solution formed in this reaction is 4.06 J ^-1 C^-1 and the caloimeter constant is 7J C^-1, calculate enthalpy change for the quantity of zinc reacted. Be sure to follow the significant figures convention in the answer you report.
