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