An excess of zinc metal is added to 50.0mL of a 0.100 M AgNO3solution in a constant-pressure calorimeter (styrofoam cup). As aresult of the reaction

Zn(s) + 2Ag+(aq) --> Zn2+(aq) + 2Ag(s)

the temperature rises from 19.25C to 22.17C. If the heat capacityof the calorimeter is 98.6J/C, calculate the enthalpy change forthe above reaction on a molar basis. Assume that the density andspecific heat of the solution are the same as those for water, andignore the specific heats of the metals.

Where does the heat capacityof the calorimeter is 98.6J/C come into play - or doesn't it?
