The heat gained by the ice melted the ice and raised the temperature of the melted ice from its initial temperature to the final temperature of the water in the calorimeter.
Use this information to calculate the heat of fusion per gram of ice for each trial.
Enter your values using the correct number of significant figures. This may be 2 or 3 digits.

heat capacity of calorimeter =56.4 J/C

q(calorimeter)+q(water) = -( q(ice)+q(ice water) )
