A solution contains non-volatile solute of molecular mass `M_p`. Which of the following can be used to calculate molecular mass of the solute in terms of osmotic pressure (m = Mass of solute, V = Volume of solution and `pi` = Osmotic pressure)

Options

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

Answer

B

Explanation

`pi=(n)/(V)RTimpliesM_(P)=((m)/(V))(RT)/(pi)`
