The Acid and Base Molarity Calculator provides lab-ready directions on how to prepare an acid or base solution of a specified Molarity (M) from a concentrated acid or base solution.

The molarity of a solution is defined as the number of moles of solute per liter of solution. Molarity facilitates easy dilution of a solution using the dilution formula, where the initial concentration multiplied by the initial volume equals the final concentration multiplied by the final volume (M1V1=M2V2). Multiplying the molarity by the volume gives the total moles of the material, which can then be diluted to any lower concentration.

Calculated results are copyable to other apps.

Molarity= [(% x d) / MW] x 10

- % = Weight Percentage,
- d = Density,
- MW = Molecular Weight.

Molarity refers to:
1) The number of moles of solute per liter of solution.
2) The number of moles of a solute dissolved in a liter of solvent. Note: Be careful not to confuse molarity with molality. Molarity is represented by a small "m," whereas molality is represented by an uppercase "M."
3) The number of moles of solute in a liter of solution.

Calculate the Molarity for the given details.
Weight percentage = 250
Density = 50
Molecular weight/Formula Weight = 25

Apply Formula:
Molarity = [(% x d) / MW] x 10
Molarity = 5000

A waste of space and money

Buggy - on 12.1.4, it took me a dozen attempts to use the program without crashing. Just tapping on the acid/base drop down would cause immediate crashing. Once it actually got beyond that point, I found that the calculation wasn’t even correct. To make 4L 5M NH4OH I need to add 1.3mL of stock solution to 1mL water? Uhhh...
