Concept explainers
Interpretation:
“Mole fraction and the vapor pressure of chloroform above the new solution.” should be identified.
Concept introduction:
a) The relation between partial pressure in vapor and pure vapor pressure is given by Raoult’s law, According to Raoult’s law
where,
xs = mole fraction of solvent
P0 = vapor pressure of pure solvent
Ps = vapor pressure of solution
b) As mentioned in question if we have condensed the vapor then the mole fraction of chloroform in new solution will be equal to the mole fraction calculated for vapor in first solution.
c) Molar mass of CCl4 is
d) Molar mass of CHCl3 is
Given:
Temperature is 316 K
Vapor pressure of pure chloroform is 0.526 atm
Vapor pressure of pure carbon tetrachloride is 0.354 atm.

- Calculate the molality of a solution made by dissolving 115.0 g ethylene glycol, HOCH2CH2OH, in 500. mL water. The density of water at this temperature is 0.978 g/mL. Calculate the molarity of the solution.arrow_forwardThe freezing point of 0.109 m aqueous formic acid is 0.210C. Formic acid, HCHO2, is partially dissociated according to the equation HCHO2(aq)H+(aq)+CHO2(aq) Calculate the percentage of HCHO2 molecules that are dissociated, assuming the equation for the freezing-point depression holds for the total concentration of molecules and ions in the solution.arrow_forwardRefer to Figure 13.10 ( Sec. 13-4b) to answer these questions. (a) Does a saturated solution occur when 65.0 g LiCl is present in 100 g H2O at 40 C? Explain your answer. (b) Consider a solution that contains 95.0 g LiCl in 100 g H2O at 40 C. Is the solution unsaturated, saturated, or supersaturated? Explain your answer. (c) Consider a solution that contains 50. g Li2SO4 in 200. g H2O at 50 C. Is this solution unsaturated, saturated, or supersaturated? Explain your answer. Figure 13.10 Solubility of ionic compounds versus temperature.arrow_forward
