moles of copper ions that react is 0.0125
calculate the heat evolved in the reaction(assume the final vol. of the solution after the zinc is added is 50cm³ assume that the specific heat capacity of the solution is 4.18J k-1g and its density is 1.00g cm3)

This is what i managed to work out is any of this correct please assist me!!
 q=mc :delta:T      50.0X4.18X10.8 = 2257.2
                               2257.2/0.0125= 180576 joules per mole.

I now need to answer using these two calculations the molar enthalpy change for the reaction;
Zn+Cu²⁺----> Zn²⁺+ Cu

Give your answer in KJ mol
and complete the expression  :delta:H=..KJmol


please help me as this is really confusing me! any help or advice would be much appreciated!
