Which one of the following is the expression of Raoult's law?
$p$ = vapour pressure of pure solvent
$p_s$ = vapour pressure of the solution
$n$ = number of moles of the solute
$N$ = number of moles of the solvent
$p$ = vapour pressure of pure solvent
$p_s$ = vapour pressure of the solution
$n$ = number of moles of the solute
$N$ = number of moles of the solvent
- A$\frac{p - p_s}{p} = \frac{n}{n + N}$
- B$\frac{p_s - p}{p} = \frac{N}{N + n}$
- C$\frac{p - p_s}{p_s} = \frac{N}{N - n}$
- D$\frac{p_s - p}{p_s} = \frac{N - n}{N}$
