Question

An ideal solution is obtained by dissolving n moles of non-volatile, non-electrolyte solute in N moles of solvent. If the vapour pressure of solution is P and the vapour pressure of pure solvent is ‘Po ’, then

Options

A.$\frac{P^{o} - P}{P} = \frac{n}{N}$
B.$\frac{P^{o} - P}{P^{o}} = \frac{n}{N}$
C.$\frac{P^{o} - P}{P^{o}} = \frac{N}{n}$
D.$\frac{P^{o} - P}{P} = \frac{N}{n}$

Solution

$\frac{P^{o} - P}{P} = \frac{n_{\text{solute}}}{n_{\text{solvent}}} = \frac{n}{N}$
