To calculate the amount of energy required to melt 50 grams of ice at 0C, we can use the formula:Energy Q = mass m heat of fusion Lf where:- Energy Q is the amount of energy required, in joules J - mass m is the mass of the ice, in grams g - heat of fusion Lf is the energy required to change 1 gram of ice at 0C to 1 gram of water at 0C, in joules per gram J/g Given the mass of ice m is 50 grams and the heat of fusion Lf is 333.55 J/g, we can plug these values into the formula:Q = 50 g 333.55 J/gQ = 16677.5 JTherefore, the amount of energy required to melt 50 grams of ice at 0C is 16,677.5 joules.
