1. What amount of energy in Joules is necessary to melt a 14.5 gram piece of ice at 0 C to form liquid water at the same temperature 0? heat of fusion of water is 6.01 kJ/mol or 333 J/g The specific heat of H2O(l) is approximately constant at 4.18 J/g*C C. Enter your answer in scientific notation with no units.

2. (This one I got) What amount of energy, in Joules, must be removed from 127.0 grams of water at 75.5 to cool it to 10.0 C? Enter your answer in scientific notation without units. answer is (3.49×10^4)

3.What is the final temperature, (in Degrees C), after a 14.5 gram piece of ice at 0 C is placed into a styrofoam cup with 127.0 grams of water initially at 75.5 C? The mass of the ice, and the temperature and mass of the hot water are the same as in the previous two questions. Assume no loss or gain of heat from the surroundings. Enter your answer in scientific notation without units.
