  1. Molarity (video) | 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.

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

    You can mix a smaller amount of a liquid into a larger amount of another liquid and use molarity where the minor liquid is the solute and the major liquid is the solvent.

  3. 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 …

  4. 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 …

  5. 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 …

  6. pH, pOH, and the pH scale (article) | Khan Academy

    Step 2: Calculate molarity of H + after dilution The molarity of the diluted solution can be calculated by using the moles of H + from the original solution and the total volume after dilution.

  7. 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.

  8. Solutions, acids, and bases | High school chemistry | Khan Academy

    Learn Activity: How can solubility principles help us detect and eliminate chemical contaminants in our water supply? Molarity Use molarity to calculate the concentration of a solution. Understand the …
