A winter skier made a hand warmer by placing 1.0 mol of sodium acetate, NaCH3CO2 (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?
O A. 6.57 x 104 J/mol
O B. 1.12 x 10² J/mol
O C. 5.64 x 104J/mol
O D. 9.25 x 103 J/mol
