What is vapour pressure of a solution containing $1 mol$ of a non-volatile solute in $36 g$ of water? $(P_{1}^{0} = 400 mm Hg)$

Options:

Answer:

Solution:

$\frac{P ^{\circ} - P _{S}}{P ^{\circ}} = X_{solute} = \frac{N _{solute}}{N _{solute} + N _{water}} N_{water} = \frac{36}{18} = 2 \frac{400 - P _{s}}{400} = \frac{1}{1 + 2} (400 - P_{s}) \times 3 = 400$
