An ice cube of mass 9.0 g is added to a cup of coffee, whose temperature is 85^\circ C and which contains 120 g of liquid.

An ice cube of mass 9.0 g is added to a cup of coffee, whose temperature is 85^circ C and which 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 {{rm{kJ}}}/{{rm{mol}}}. Find the temperature of the coffee after the ice melts.
