How do you calculate the osmotic pressure of a solution?

Sample interview questions: How do you calculate the osmotic pressure of a solution?

Sample answer:

Calculating Osmotic Pressure

• Definition of Osmotic Pressure: The pressure required to prevent the net movement of water across a semipermeable membrane that separates two solutions of different concentrations.

• Mathematical Formula:

π = MRTc

where:

• π is the osmotic pressure (Pa)
• M is the molarity of the solution (mol/L)
• R is the ideal gas constant (8.314 J/mol·K)
• T is the absolute temperature (K)
• c is the concentration of the solute (mol/L)

Steps for Calculation:

1. Determine the molarity of the solution: This can be calculated from the concentration of the solute using:

Molarity = Weight of Solute (g) / Molar Mass (g/mol) × Volume of Solution (L)

1. Convert temperature to Kelvin: If n… Read full answer
