This is a dry lab assessment for synthesis of Nylon 6,6. I
believe I understand how to calculate the limiting reagent (Q1) and
have determined it to be adipic acid. I’m stuck on calculating the
theoretical yield (Q2) and need some help getting through the
bullet points of the procedure used to answer the question.
Thanks!

Ethylene glycol is used in automobile radiators as an antifreeze. Use the following information to determine the freezing point of an antifreeze solution made by mixing 2.5 L of ethylene glycol with 2.5 L of water. Ethylene glycol is essentially nonvolatile and it does not dissociate in water. Molar mass of ethylene glycol = 62.1 g/mol; density of ethylene glycol = 1.11 g/mL; density of water = 1.00 g/mL; Kf for water = 1.86 degrees Celsius kg/mol

Several solar collectors are used to obtain energy from the sun to heat ethylene glycol. The ethylene glycol flows at 0.006 m3/s from the collectors to a plate and frame heat exchanger. The ethylene glycol enters the heat exchanger at 24°C, where it transfers heat to fresh water. The water enters the exchanger at 0.005 m3/s, with a temperature of 10°C. The plate height is 1.5 m, and a plate spacing of 4.3 mm. There are 15 plates made of...
