I can't find the enthalpy of fusion for one of my trials. Info I have: 3,160 heat absorbed and 55g of ice melted (410g for the calorimeter w/ nothing -- 452g in the calorimeter w/ water -- 500g in the calorimeter w/ ice and water -- then I poured out the water after stirring and got 445g for the remaining ice). Also, I'm not sure what it means when it says I need to find the percent error from the accepted enthalpy of fusion of water of 334 J/g?
