Question

a freezing point of 42.1°C. AT-ikm. (Show work below. A) 2.99°C B) 6.21°c C) 35.9°c D) 39.1°C E) 48.3°C Freezrng/memng ADD negauve boiling dont 19. Calculate the freezing point of a solution of 400.0 g of ethylene glycol (C2H602) dissolved in 600.0 g of water. Kf= 1.86°C/m and Kb = 0.512°C/m. (Show work below.) A) 80.0 B)-5.5°C C) 20.0°C D) -20.0°C E) 5.5°C Remember water freezes at 0° C 20. Choose the aqueous solution that has the highest boiling point. These are all solutions of nonvolatile solutes and you should assume ideal van't Hoff factors where applicable. A) 0.100 m NaNO3 B) 0.100 m Li2S04 c) 0.200 m C3H803 D) 0.060 m NasPO4 E) They all have the same boiling point.
