For a dilute solution containing a nonvolatile solute, the molar mass of solute evaluated from the osmotic pressure measurement is given as:

A

`M_(2) = (m_(2))/(V)(RT)/(pi)`

B

`M_(2) = (m_(2))/(V)(pi)/(RT)`

C

`M_(2) = m_(2)(RT)/(pi)`

D

`M_(2) = m_(2)(pi)/(RT)`

Text Solution

Verified by Experts

The correct Answer is:
A
`pi = (m_(2) xx R xx T)/(M_(2) xx V) rArr M_(2) = (m_(2)RT)/(piV)`
