A winter skier made a hand warmer by placing 1.0 mol of
sodium acetate, NaCH, CO, (molar mass = 82.03 g/mol), in a
plastic wrap pouch within a container of water. The skier
then opened the plastic wrap pouch, allowing the sodium
acetate to mix with the water. This formed a 500 g solution
with a temperature change of 27°C. What is the heat of
solution given the specific heat of water is 4.18 J/g.°C?
