1) Calculate the final temperature of 63 mL of ethanol initially at 11 °C upon absorption of 527 J of heat. (density of ethanol = 0.789 g/mL)?
2) 225.0 mL of ethanol (density = 0.789 g/mL) initially at 7.4°C is mixed with 32.1 mL of water (density = 1.0 g/mL) initially at 25.3°C in an insulated beaker. Assuming that no heat is lost, what is the final temperature of the mixture?
