Molality: Molality (m) is defined as the number of moles of the solute per kilogram (kg) of the solvent and is expressed as:
Molality (m) =
molality are independent of temperature, whereas molarity is a function of temperature. This is because volume depends on temperature
and the mass does not.
Henry’s law states that “the partial pressure of the gas in vapour phase (p) is proportional to the mole fraction of the gas (x) in the solution” and is expressed as: p = KHx
where KH henry's constant
