CaCl2 (MM = 110.98 g/mol) is used as road salt in the winter to minimize the accumulation of ice on roads. What is the ΔH°, in kJ/mol, for the dissolving of CaCl2in water if the addition of 111 g of CaCl2 causes 889 g of water to increase in temperature by 19.6 °C? The specific heat capacity of water is 4.184 J/g°C.
