Osmosis video - Molarity and dilutions

Molarity and dilutions are important concepts in chemistry, particularly when it comes to concentrations of solutions. Molarity is a unit of concentration that is expressed as moles per liter (M). It describes the number of moles of a solute that are present in one liter of solution. Dilution is the process of reducing the concentration of a solution by adding more solvent. This can be done in order to make the solution weaker, or to create different concentrations for various purposes.
