AIPMT PRELIMS 2002 Chemistry Osmotic Pressure MCQ Question
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 :-
M₂ = (m₂/π) VRT
M₂ = (m₂/V) RT/π
M₂ = (m₂/V) πRT
M₂ = (m₂/V) π/RT
Correct Answer
Detailed Explanation
Using the formula for osmotic pressure: π = (n/V)RT, where n = m₂/M₂, rearranging gives M₂ = (m₂/V)RT/π.
