4) How many grams of ice at -17C must be added to 741 grams of water that is initially at 4) a temperature of 70C to produce water at a final temperature of 12C? Assume that no heat is lost to the surroundings and that the container has negligible mass. The specific heat of liquid water is 4190 \"kg - C and of ice is 2000 J/kg - C. For water the normal melting point is 0C and the heat of fusion is 334 x 103l/kg. The normal boiling point is 100 C and the heat of vaporization is 2.256 x 106 \"kg
