To calculate the energy required to melt 50 grams of ice at 0 C to water at the same temperature, we need to use the enthalpy of fusion of water, which is 6.01 kJ/mol.First, we need to convert the mass of ice to moles. The molar mass of water is 18.015 g/mol.Moles of ice = 50 g / 18.015 g/mol = 2.776 molesNow, we can use the enthalpy of fusion to calculate the energy required to melt the ice:Energy required = moles of ice enthalpy of fusion Energy required = 2.776 moles 6.01 kJ/mol = 16.681 kJTherefore, the amount of energy required to melt 50 grams of ice at 0 C to water at the same temperature is 16.681 kJ.
