What formulas do I use for this problem and what do the formulas mean and how to solve this problem step by step I am confused In the laboratory 31 0 g of ice at 0 degrees celsius is placed into an 85 0 g copper calorimeter cup that contains 155 g of water at an initial temperature of 23 0 degrees celsius After the ice melts the final temperature of the water is found to be 6 25 degrees celsius From this laboratory data find the heat of fusion of water and the percentage error between the standard value and this experimental value
