  1. 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.

  2. 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.

  3. 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.

  4. 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 …

  5. 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 …

  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. Moles and molar mass (practice) | Khan Academy

    Using the information in the table, calculate the number of moles in a 2.03 kg sample of citric acid (C A 6 H A 8 O A 7 ). Write your answer using three significant figures.

  8. Molarity vs. osmolarity (video) | Khan Academy

    I want to talk about the difference between the two words-- molarity, M-O-L-A-R-I-T-Y, molarity-- and a word that's very similar, osmolarity. And I'm going to do it with a little example, because I think …

  9. 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 …

  10. 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.
