An ice cube tray contains enough water

Reference no: EM13551808

An ice cube tray contains enough water at 22.0 °C to make 18 ice cubes that each have a mass of 30.0g. The tray is placed in a freezer that uses CF2Cl2 (difluorodichloromethane, R-12) as a refrigerant. The latent heat of vaporization of CF2Cl2 is 158 J/g. What mass of CF2Cl2 must be vaporized in the refrigeration cycle to convert all the water at 22.0 °C to ice at -5.0°C? Assume: Heat capacity of ice = 2.08 J/g-°C, Heat capacity of water = 4.18 J/g-°C, latent heat of fusion for ice = 333 J/g.
