In an insulated vessel, 250 g of ice at 0C is added to 600 g of water at 18C. How much ice remains when the system reaches equilibrium? Assume the heat of fusion of ice is 79.7 cal/g and its specific heat is 0.5 cal/gC. The heat of vaporization of water is 540 cal/g and its specific heat is 1 cal/gC. Note: someone else got 114, however that doesn't add up being you have to use the heat of fusion and heat of evaporation given
