van’t Hoff factor, to account for the extent of dissociation or association. This factor i is defined as:
Answer:
The solutions which obey Raoult’s law over the entire range of concentration are known as ideal solutions. The ideal solutions have two other important properties. The enthalpy of mixing of the pure components to form the solution is zero and the volume of mixing is
also zero, i.e.,
ΔmixH = 0, ΔmixV = 0
Molarity: Molarity (M) is defined as number of moles of solute dissolved in one litre (or one cubic decimetre) of solution,
Molality: Molality (m) is defined as the number of moles of the solute per kilogram (kg) of the solvent and is expressed as:
molality are independent of temperature, whereas molarity is a function of temperature. This is because volume depends on temperature and mass does not.
