Q. The vapour pressure of water at room temperature is 23.8 mm Hg. The vapour pressure of an aqueous solution of sucrose with mole fraction 0.1 is equal to

Solutions

Solution:

$\Delta P = p^{\circ} \times x_B = 23.8 \times 0.1 = 2.38$
$\therefore $ Vapour pressure of sol. = 23.8 - 2.38
= 21.42 mm Hg.
