A solution contains non volatile solute of molecular mass `M_(2)`. Which of the following can be used to claculate the molecular mass of solute in terms of osmotic pressure ?

Options

A. `M_(2)=[m_(2)/(pi)]VRT`
B. `M_(2)=[w_(2)/(V)](RT)/(pi)`
C. `M_(2)=[m_(2)/(V)]nRT`
D. `M_(2)=[w_(2)/(V)]pi/(RT)`

Answer

B

Explanation

`m_(2)=[W_(2)/(V)](RT)/(pi)`
