Dilution Calculations Previously in this lesson, the concentration calculations that we have done essentially involved preparing a solution from scratch.
Chemists use many different units when expressing concentration; however, one of the most common units is molarity. Molarity M is the concentration of a solution expressed as the number of moles of solute per liter of solution: Molarity M moles solute liters solution For example, a 0.
In order to calculate the molarity of a solution, you need to know the number of moles of solute and the total volume of the solution. Calculate the number of moles of solute present. Calculate the number of liters of solution present. Divide the number of moles of solute by the number of liters of solution.
Instead of calculating the moles of solute and liters of solution present individually, you can also string all the calculations together in one problem: Divide the amount of solute by the volume of solution regardless of the initial units given. Use dimensional analysis to convert the amount of solute to moles of solute.
Use dimensional analysis to convert the volume of solution to liters of solution if necessary. The following example will illustrate both methods. What is the molarity of a solution prepared by dissolving Many solutions contain one component, called the solvent, in which other components, called solutes, are dissolved.
An aqueous solution is one for which the Molarity and Dilutions - Chemistry LibreTexts.
