An ice cube of mass 9.0 g is added to a cup of coffee. The coffee's initial temperature is 90 C and the cup contains 120 g of liquid. Assume the specific heat capacity of the coffee is the same as that of water. The heat of fusion of ice (the heat associated with ice melting) is 6.0 kJ/mol. Find the temperature of the coffee after the ice melts.
