Vapour pressure of a solution containing `6.0 gm` of a non-volatile solute in `180 gm` water at `25^(@)C` is `20` torr. If `1 "mole"` of water is further added, the vapour pressure at `25^(@)C` increases by `0.02` torr. Identify the correct information :

A

The molar mass of solute is `54 gm//"mol"`.

B

The vapour pressure of pure water at `25^(@)C` its `(182)/(9)` torr.

C
