InterviewSolution

1.	The vapour pressure of acetone at 20∘C is 185 torr. When 1.2 g of a non-volatile substance was dissolved in 100 g of acetone at 20∘C, its vapour pressure was 183 torr. The molar mass (gmol−1) of the substance is:
Answer» The vapour pressure of acetone at $20^{\circ} C$ is 185 torr. When 1.2 g of a non-volatile substance was dissolved in 100 g of acetone at $20^{\circ} C$ , its vapour pressure was 183 torr. The molar mass $(g m o l^{- 1})$ of the substance is:
