The ΔH per mole of CaCl2 is 81.0 kJ. Calculate the final temperature of an aqueous solution if 30 g of CaCl2 are added to 100 g of water at 23oC. Assume that the specific heat of the solution is the same as that of water

Q=mc∆t
where
Q=heat
m= total mass
c=specific heat of solution= 4.186 x 10^3 kilojoule/gram °C
∆t=final temp initial temp
solve for final temperature
