A solution contains non-volatile solute of molecular mass`M_(2)`which of the following can be used to calculate the molecular mass of solute in terms of osmotic pressure?
(`m_(2)` =mass of solute,V=volume of solution,`pi` =osmotic pressure)

Options

A. `M_(2)=((m_(2))/(pi))VRT`
B. `M_(2)=((m_(2))/(V))(RT)/(pi)`
C. `M_(2)=((m_(2))/(V))piRT`
D. `M_(2)=((m_(2))/(V))(pi)/(RT)`

Answer

B

Explanation

We know ,`pi=CRT`
`!= =(n)/(V)RT,piV=(m_(2))/(M_(2))RT`
