To calculate the energy change when 50.0 g of ice melts, we can use the equation:
Energy Change = Mass of Substance x Heat of Fusion.
1. Convert the mass of ice from grams to mols:
50.0 g / 18 g/mol = 2.77 mol
2. Calculate the energy change using the heat of fusion:
Energy Change = 2.77 mol x 334 kJ/mol = 925.18 kJ
Therefore, the energy change when 50.0 g of ice melts is 925.18 kJ.
