Question
![[16] At a checkpoint a white powdery substance was found in a car and suspected to be cocaine (303.35 g/mol). When a 2.0-g
sample of the white powder is dissolved in 500-mL of water, the resulting osmotic pressure at 300K is found to be 217 mmHg.
Determine the molar mass of the substance. Should the driver of the vehicle be arrested for possession of cocaine? Justify your
response.

Expert Solution
Step 1: Osmotic pressure definition
Osmotic pressure is the minimum pressure required to prevent the flow of the solvent through semi permeable membrane.
Here we have to calculate molar mass of the unknown white powdery substance with the help of Osmotic pressure.
