The vapor pressure of pure acetone (C3H6O) is 216 torr
svetoff [14.1K]

The mole fraction of acetone (C₃H₆O) is 0.333

<h3>Data obtained from the question </h3>
  • Mole of C₃H₆O = 0.1 mole
  • Mole of CHCl₃ = 0.2 mole
  • Mole fraction of C₃H₆O =?

<h3>How to determine the mole fraction </h3>

Mole fraction of a substance can be obtained by using the following formula:

Mole fraction = mole / total mole

With the above formula, we can obtain the mole fraction of C₃H₆O as follow:

  • Mole of C₃H₆O = 0.1 mole
  • Mole of CHCl₃ = 0.2 mole
  • Total mole = 0.1 + 0.2 = 0.3 mole
  • Mole fraction of C₃H₆O =?

Mole fraction = mole / total mole

Mole fraction of C₃H₆O = 0.1 / 0.3

Mole fraction of C₃H₆O = 0.333
