Question

An ethylene glycol and water solution freezes at –7.9921°C. The freezing point depression constant for water is 1.86°C m-1. (Note that “m” is the unit symbol for molality and is identical to mol kg-1: i.e., 1 m = 1 mol kg-1.) Use this information to calculate the molal concentration of ethylene glycol in the solution

Answer 1

The measurement of the boiling point of water does not change its identity or composition. L 0.556 L (d) 3 2 3 10.6 kg 1000 g 1 10 m 1 kg 1 cm1 m. pounds and grams cancel, and the unit milligrams is obtained in your answer. Statement (a) water colorless liquid freezes at 0°C (b) carbon black solid ...
