AIPMT PRELIMS 2002 Chemistry Osmotic Pressure MCQ Question

Type: MCQ-numerical-Medium-Class 12

A solution contains non volatile solute of molecular mass M₂. Which of the following can be used to calculate the molecular mass of solute in terms of osmotic pressure :-

A

M₂ = (m₂/π) VRT

B

M₂ = (m₂/V) RT/π

C

M₂ = (m₂/V) πRT

D

M₂ = (m₂/V) π/RT

Correct Answer

Option B

Detailed Explanation

Using the formula for osmotic pressure: π = (n/V)RT, where n = m₂/M₂, rearranging gives M₂ = (m₂/V)RT/π.
