The most common equation is: i = moles of particles in solution / moles dissolved solute. Because solutes don’t always fully dissociate in solution, there is another relation that is often used: i = 1 + α ( n – 1)
WebIt is a colligative property and is dependent on the concentration of solute particles in the solution. Osmotic pressure can be calculated with the help of the following formula: π = iCRT. Where, π is the osmotic pressure. i is the van’t Hoff factor. C is the molar concentration of the solute in the solution. R is the universal gas constant. WebPolarizabilities are normally expressed in cgs units of cm 3. Ground-state polarizabilities are in the range of 10 –24 cm 3 = 1 Å 3 and hence are often given in Å 3 units. Theorists tend to use atomic units of a03 where a0 is the Bohr radius. The conversion is α (cm 3) = 0.148184 × 10 -24 × α ( a03 ).
