Question

Chloromethane (84.93 g/mol) is weighted and dissolved in a nonvolatile solvent and maintain the total number of moles of solute and solvent at 2.2 mole total. Then the vapor pressure of chloromethane is measured.

(a) Fill in the blanks for the mole fractions of chloromethane

mass(g)	2.06	4.73	7.38	10.1	12.7
x
p(kPa)	25	50	75	100	125

(b) From the above data, can one estimate the value for the Henry’s Law constant of chloromethane in this particular solvent under the given conditions?

K_H = ___________ kPa
