Find Enthalpy of  following solutions in water in kJ/g: kcl and naoh.
6.28 g of naoh is added to 75ml/g of water. The Initial temp of water (in Celsius) is 21.4, and its final temp is 40.4. Also for this solution I got Energy change to be 5965.05J, I do not know it that is correct. For energy change we were told to use m*c*t.

Furthermore, in a separate reaction, 5.98g of kcl is added to 75ml/g of water. Initial temp of water (in Celsius) is 21.3, and the Final temp (in Celsius) of water is 16.3. For this solution I got Energy change to be -1569.75J.

I do not know how to find the Enthalpy of each of the solutions, please help me.
Thanks
