If 55.0 mL of ethanol (density = 0.789 g/mL ) initially at 6.0 ∘ C is mixed with 55.0 mL of water (density = 1.0 g/mL ) initially at 28.6 ∘ C in an insulated beaker, what is the final temperature of the mixture, assuming that no heat is lost? ( C EtOH =2.42J/(g⋅ ∘ C). ) Express the temperature in degrees Celsius to three significant figures.
