Molarity vs. molality (video) | Khan Academy
Learn how molarity and molality differ! The molality of a solution is equal to the moles of solute divided by the mass of solvent in kilograms, while the molarity of a solution is equal to the moles of solute …
Dilutions (video) | Molarity | Khan Academy
The dilution equation (M1*V1) = (M2*V2) is used to calculate the molarities and volumes required for the dilution. This often starts with a concentrated stock solution, which is then diluted to achieve the …
