Vapour pressure of dilute aqueous solution of glucose is 750 mm of mercury at

Vapour pressure of dilute aqueous solution of glucose is 750 mm of mercury at 373K. The mole fraction of solute is

Options

(a) 1/76
(b) 1/7.6
(c) 1/38
(d) 1/0.1

Correct Answer:

1/76

Explanation:

p(s) = p⁰(1 – x₂).

⇒ 750 = 760(1 – x₂) or 750/760 = 1 – x₂, or 750/760 -1 = -x₂

⇒ x₂ = 1/76.
