We often want to be able to quantify the amount of a species that is in the solution, which is called the concentration of that species. In this article, we'll look at how to describe solutions …

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 …

A 0.674 M cobalt (II) chloride (CoCl 2 ) solution is prepared with a total volume of 0.0750 L . The molecular weight of CoCl 2 is 128.9 g mol . What mass of CoCl 2 (in grams) is needed for the …

First, calculate the number of moles of strong base required to reach the equivalence point of the titration. Then, using the mole ratio from the balanced neutralization equation, convert from …

This added acid or base also increases the volume of the solution changing the molarity of the buffer acid and base. So once we have the correct new molarities from the ICF table, they can …

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 …

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 …

Through this exercise, we will revise the various ways in which concentration of a solution can be expressed such as mass percentage, volume percentage, mole fraction, molarity and so on.

Dilution is the process of lowering the concentration of a solution by adding solvent. This process is important for preparing solutions of precise concentrations for experiments. The dilution …

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