Calculate the heat released when 300 mL of water at 20°C is mixed with 200 mL of ethanol at 25°C. The specific heat capacity of water is 4.18 J/g°C, the specific heat capacity of ethanol is 2.44 J/g°C, and the heat of mixing for water and ethanol is approximately -21 kJ/mol. Assume that both water and ethanol have a density of 1 g/mL and that the final temperature of the mixture is 22°C.
