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 = mass of solute, V = volume of solution, pi = osmotic pressure)

  1. M subscript 2 equals open parentheses m subscript 2 over pi close parentheses V R T
  2. M subscript 2 equals open parentheses m subscript 2 over V close parentheses fraction numerator R T over denominator pi end fraction
  3. M subscript 2 equals open parentheses m subscript 2 over V close parentheses pi R T
  4. M subscript 2 equals open parentheses m subscript 2 over V close parentheses fraction numerator pi over denominator R T end fraction

The correct answer is: M subscript 2 equals open parentheses m subscript 2 over V close parentheses fraction numerator R T over denominator pi end fraction
