How to calculate
Estimate ideal osmotic pressure from concentration, temperature and a supplied particle factor.
Osmotic pressure =
i*M*1000*8.31446261815324*T PaOsmotic pressure in kilopascals =
i*M*8.31446261815324*T kPaWorked example
- Van ’t Hoff factor: 1
- Molar concentration (mol/L): 0.1
- Absolute temperature (K): 298.15
- Osmotic pressure: 247,895.7 Pa
- Osmotic pressure in kilopascals: 247.9 kPa
