Question

If 50.0 mL of ethanol (density = 0.789 g/mL) initially at 6.0 ∘C is mixed with 50.0 mL of water (density = 1.0 g/mL) initially at 28.8 ∘C in an insulated beaker, what is the final temperature of the mixture, assuming that no heat is lost? (CEtOH=2.42J/(g⋅∘C).) Express the temperature in degrees Celsius to three significant figures.
