Zinc dissolves in acid according to the balanced equation.

Zn(s)+ 2H(aq)-> Zn(aq) + H2(g)

a sample of zinc is placed in a ice calorimeter. If 0.0657g of zinc causes a decrease of 0.109ml in the ice/water volume of the calorimeter, what is the enthalpy change, per mole of zinc, for the above reaction per mole of zinc.
