REVIEW QUESTIONS 1. How many grams of ethylene glycol, C,H,(OH)2, are needed per kilogram of water to protect radiator fluid against freezing down to -15°C? For water, the freezing point constant, Kp, is 1.86°C kg mol-! CH (OH), does not dissociate in aqueous solution, i = 1. 2. For benzene, CH, the freezing point constant, K, is 5.12°C kg mol-1 and its normal freez- ing point is 5.5°C. What is the freezing point of a solution containing 100.0 g of...
