An aqueous solution of methanol has vapour pressure

Vapour pressure of a solution is

A solution containing 30 g of non-volatile solute exactly in 90 g of water has a vapour pressure of 2.8 kPa at 298 K. Further, 18 g of water is then added to the solution and the new vapour pressure becomes 2.9 kPa at 298 K. Calculate: vapour pressure of water at 298 K.

An aqueous solution of methanol in water has vapour pressure:
