MCQ
The osmotic pressure of a dilute solution is given by
  • A
    $P = {P_o}x$
  • ✓
    $\pi V = nRT$
  • C
    $\Delta P = {P_o}{N_2}$
  • D
    $\frac{{\Delta P}}{{{P_o}}} = \frac{{{P_o} - P}}{{{P_o}}}$
✓

Answer

Correct option: B.
$\pi V = nRT$
b
As we know,

$\pi V = nRT$

$\pi=\frac{ n }{ V } RT$

$\Rightarrow \pi= CRT$
