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

Options

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)`

Answer

A

Explanation

`pi = (m_(2) xx R xx T)/(M_(2) xx V) rArr M_(2) = (m_(2)RT)/(piV)`
