Hey guys,
I couldn't understand this question at all! Someone please help me! I believe something is wrong with it!

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

Zn(s)+2H*(aq) --> Zn*(aq)+H2(g)
"H" charge is "+1"
"Zn" charge is"+2"
