Molarity Calculator for Solutions | Find Moles per Liter of Solution
Find the number of moles of solute present per liter of solution. Use this calculator to determine molarity from known solute amount and solution volume.
About Molarity Calculator
When chemistry problems ask how concentrated a solution is, molarity is often the first measurement that comes to mind. It tells you how many moles of solute are present in one liter of the solution.
The Molarity Calculator makes this calculation easier by connecting the amount of solute with the final solution volume. The basic formula is M = n/V, where M represents molarity, n is the number of moles of solute, and V is the solution volume in liters.
For example, 0.5 mol of solute dissolved to make 2 L of solution gives a molarity of 0.25 M.
Molarity is widely used in chemistry classes, titrations, laboratory preparation, reaction calculations, and dilution problems. One detail worth remembering is that the volume refers to the entire solution, not just the solvent added. Temperature can also affect solution volume, which is one reason molarity and molality are not interchangeable. Before calculating, convert the solution volume to liters and make sure the amount of solute is expressed in moles.
