[EXTRA CREDIT] (3 pts pоssible, questiоn will shоw аs being out of 0 pts) A hotpаck is commonly а plastic bag filled with aqueous sodium acetate solution. Upon shaking the bag, sodium acetate precipitates out of solution, releasing heat in the process to keep your hands warm. What mass of sodium acetate must precipitate out, in order for the 50.0 mL of water in the hotpack to rise in temperature from 25.0°C to 61.3°C? The heat of crystallization of sodium acetate is -19.7 kJ/mol. Assume the density of water is 0.997 g/mL, and that all heat transfer is between the sodium acetate and the water solvent. Assume the solution is dilute such that it has the same specific heat capacity as water. Show all work, using dimensional analysis where appropriate, and highlight your answer in a readable background color.
