Question

Life on planet Eitemax is tough. The surface is composed of oceans of nearly pure liquid chloroform (CHCl3). The atmosphere on Eitemax acts like an ideal gas and on a chloroform-free basis. The ambient temperature is 2F on Eitemax, and the total pressure is 610 mm Hg (torr). In one area the chloroform from the oceans has volatilized so that the atmosphere is 75% saturated with this gas, find the mole fraction of chloroform in air at this location. (Hint: Treat as a relative humidity problem).

Answer 1

0.563 is a correct value of molar fraction of chloroform.

Explanation:

Mole fraction is a unit of concentration, defined to be equal to the number of moles of a component divided by the total number of moles of a solution. Because it is a ratio, mole fraction is a unit less expression. The mole fraction of all components of a solution, when added together, will equal 1.

Mole fraction is another way of expressing the concentration of a solution or mixture. It is equal to the moles of one component divided by the total moles in the solution or mixture. Mole fraction is used in a variety of calculations, but most notably for calculating partial pressures.
