You take 227.2 g of a solid at 30.0°C and let it melt in 425 g of water. The water temperature decreases from 85.1°C to 30.0°C. Calculate the amount of heat energy required to melt this solid in units of  J/g (the heat of fusion).

◦ 123 J/g
◦ 215 J/g
◦ 431 J/g
◦ 652 J/g
◦ Cannot solve without the heat capacity of the solid
