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

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 …

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 …

In this video, we'll solve for [H₃O⁺] and pH in two different worked examples. First, we'll walk through the possible approaches for calculating [H₃O⁺] from pOH. Then, we'll find the pH of …

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 …

Practice calculations for molar concentration and mass of solute

In this video, we'll use the Beer–Lambert law to calculate the concentration of KMnO₄ in an unknown solution.

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 …

You can calculate the number of moles with grams, and find molar mass from the periodic table. number of moles = number of particles (atoms, in your case) / Avogadro's number.

Let's start with the weak acid. We're gonna use the molarity equation. Molarity is equal to moles over liters. So for our weak acid, the concentration is 2.0 molar, so we plug that in, and the …
