The method used in this experiment is difficult to apply for determining the formula weight of unknown salts in aqueous solutions. Even when accurate freezing point depressions are measured, the results are not always conclusive because there can be an undetermined parameter. Considering the information in the Introduction section, what is the best explanation for this difficulty?

City a and city b had two different temperatures on a particular day. on that day, four times the temperature of city a was 8â° c more than 3 times the temperature of city b. the temperature of city a minus twice the temperature of city b was â’3â° c. what was the temperature of city a and city b on that day? city a was 5â° c, and city b was 4â° c. city a was 3â° c, and city b was â’1â° c. city a was 8â° c, and city b was â’3â° c. city a was 5â° c, and city b was â’5â° c.
