  1. How to calculate molarity (article) | Khan Academy

    Definitions of solution, solute, and solvent. How molarity is used to quantify the concentration of solute, and how to calculate molarity.

  2. Molarity (video) | Solutions and mixtures | Khan Academy

    The most common way to express solution concentration is molarity (M), which is defined as the amount of solute in moles divided by the volume of solution in liters: M = moles of solute/liters of solution.

  3. 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 …

  4. Molarity calculations (practice) | Khan Academy

    Molarity calculations Google Classroom Microsoft Teams You might need: Calculator

  5. Molarity (video) | Mixtures and solutions | Khan Academy

    The most common way to express solution concentration is molarity (M), which is defined as the amount of solute in moles divided by the volume of solution in liters: M = moles of solute/liters of solution.

  6. Dilution (video) | Solutions and mixtures | Khan Academy

    We can relate the concentrations and volumes before and after a dilution using the following equation: M₁V₁ = M₂V₂ where M₁ and V₁ represent the molarity and volume of the initial concentrated solution …

  7. Determining solute concentration by acid–base ... - Khan Academy

    Then, using the mole ratio from the balanced neutralization equation, convert from moles of strong base to moles of acid. Finally, divide the number of moles of acid by the given volume of the acid solution …

  8. Acid–base titrations (video) | Khan Academy

    The short cut equation is known as the dilution formula. For any equation we use in science, the only requirement regarding the units is that they agree with each other. What that means if that the units …

  9. Calculating concentration using the Beer–Lambert law (worked …

    The Beer–Lambert law relates the absorption of light by a solution to the properties of the solution according to the following equation: A = εbc, where ε is the molar absorptivity of the absorbing …

  10. Molarity vs. molality (video) | Khan Academy

    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 divided by the volume of solution in liters.
