A 12.5 g ice cube has a temperature of -15C. This ice cube completely melts when it is placed in 855g of liquid ethanol (C2H5OH). If the initial temperature of the ethanol was 22.5C and the heat capacity of liquid ethanol is 2.44 J/gC, what is the final temperature of this water/ethanol mixture? (Note: Assume there are no chemical interactions between the water and the ethanol that affect the temperature.)
