The freezing point of ethanol CH3 CH₂ OH is -117.30 °C at 1 atmosphere. A nonvolatile, nonelectrolyte that dissolves in ethanol is saccharin.

Solutions of hydrogen in palladium may be formed by exposing Pd metal to H₂ gas. The concentration of hydrogen in the palladium depends on the pressure of H₂ gas applied, but in a more complex fashion than can be described by Henry's law. Under certain conditions, 0.56 g of hydrogen gas is dissolved in 197 g of palladium metal. (The density of the resulting solution is 11.7 g/cm³.) (a) Determine the molarity of this solution.

Determine the molal concentration of NaCl solution in water that has a freezing point of -2.1 degree celsius. Kf= 1.86 degree celsius /m for water.

When 225. of urea (CH,N,0) are dissolved in 1200. g Oof a certain mystery g liquid x, the freezing point of the solution is 8.4 °c lower than the freezing point of pure x. On the other hand, when 225. g of sodium chloride are dissolved in the same mass of x, the freezing point of the solution is 14.5 °C lower than the freezing point of pure x. olo Ar Calculate the van't Hoff factor for sodium chloride in x. Be sure your answer has a unit symbol, if necessary, and is rounded to the correct number of significant digits. i = |
