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
