Foundations: The Van 't Hoff Equation The calculation of osmotic pressure for dilute solutions is elegantly described by the Van 't Hoff equation, which draws a direct analogy to the ideal gas law. 44 g/mol), which yields 0.
Using the Van 't Hoff Equation to Calculate Osmotic Pressure
15 to the Celsius value. Limitations and the Van 't Hoff Approximation.
This relationship is expressed as π = iCRT, where 'i' is the van 't Hoff factor, 'C' is the molar concentration in moles per liter, 'R' is the ideal gas constant, and 'T' is the temperature in Kelvin. Select the correct value for the ideal gas constant (R).

Convert the temperature of the solution to Kelvin by adding 273. The Role of the Van 't Hoff Factor The van 't Hoff factor (i) is a critical multiplier in the equation that accounts for the number of particles a solute dissociates into in solution.
