Required information A 0.9- L glass of water at 20C is to be cooled with ice to 5C. The density of water is 1kg/L, and the specific heat of water at room temperature is c=4.18kJ/kgC. The specific heat of ice at about 0C is c=2.11 kJ/kgC. The melting temperature and the heat of fusion of ice at 1atm are 0C and 333.7kJ/kg. Determine how much ice needs to be added to the water, in grams, if the ice is at 0C. The amount of ice that needs to be added is g
