1.	The vapour pressure of pure water at 30∘C is 31.50 mm Hg. When 3.0 g of a non-volatile solute was dissolved in 54 g of water, the vapour pressure of the solution was found to be 31.30mm Hg. Calculate the molar mass of the solute.
Answer» The vapour pressure of pure water at $30^{\circ} C$ is $31.50 mm Hg$ . When 3.0 g of a non-volatile solute was dissolved in 54 g of water, the vapour pressure of the solution was found to be $31.30 m m H g$ . Calculate the molar mass of the solute.
