An ethylene glycol solution contains 19.3g of ethylene glycol (c2h6o2) in 82.4ml of water.
(a) compute the freezing point of the solution. (assume a density of 1.00 g/ml for water.)
(b)compute the boiling point of the solution. (assume a density of 1.00 g/ml for water.)
express your answer using five significant figures.

Explanation:

1. Calculate the molal concentration of ethylene glycol

2. Calculate the freezing point

The formula for the freezing point depression ΔTf by a nonelectrolyte is

3. Calculate the boiling point

The formula for the boiling point elevation ΔTb by a nonelectrolyte is

the temperature of the gas, in k, not celsius.

un recipient conține 6,4 moli de gaz. gazul hidrogen reprezintă 25% din totalul kilometrilor din container. în cazul în care presiunea totală este de 1.24 atm ceea ce este
