The heat of fusion of the ice is the amount of energy that is required in order to melt one gram of ice. In this item, in order to solve for the heat of fusion, we simply have to divide the given energy by the mass. 
                     heat of fusion = 16650 J / 50 g = 333 J/g
Thus, the heat of fusion of the ice is 333 J/g.
