Difference between Molarity and Molality
Molarity |
Molality |
Moles of solute In the relationship with the volume of solvent is called Molarity. | Moles of solute is in the relationship with mass of solvent is called molality. |
Amount of substance In the particular volume of solvent is molarity. | Amount of substance dissolved In the particular mass of solvent is molality |
Molarity is denoted by “M”. | Molality is denoted by “m” |
Equation of Molarity is
M = moles solute/ liter solution. |
Equation of molality is
m = moles of solute/ kg of solvent |
It has unit
Moles/ liter. |
It has unit
Moles /kg. |
Molarity depend on volume of whole solution. | Molality depend on mass of solvent. |
