Question

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?
Here `n_(2)=` mass of solute, V = volume of solution, `pi =` osmotic pressure.
A. `Mp=((m)/(pi))VRT`
B. `Mp=((m)/(V))(RT)/(pi)`
C. `Mp=((m)/(V))(pi)/(RT)`
D. `Mp=((m)/(V))pi RT`

Answer 1

Correct Answer - B
`pi=(n)/(V)RT rArr M_(P)=((m)/(V))(RT)/(pi)`
