A solution containing 30g of a non-volatile non-electrolyte solute exactly in 90g water has a vapour pressure of `2.8 kPa` at 298K. Further, 18g of water is then added to solution, the new vapour pressure becomes `2.9kPa` at 298K. The solutions obey Raoult's law and are not dilute, molar mass of solute is
