Posted by MD on Wednesday, February 22, 2012 at 8:00pm.

25.6 {\rm mL} of ethanol (density =0.789 {\rm g}/{\rm mL}) initially at 8.0^\circ {\rm C} is mixed with 39.5 {\rm mL} of water (density = 1.0 {\rm g}/{\rm mL}) initially at 23.1^\circ {\rm C} in an insulated beaker.

Assuming that no heat is lost, what is the final temperature of the mixture?
