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. Formula: Molarity= [(% x d) / MW] x 10 Where: - % = 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. Example: Calculate the Molarity for the given details. Weight percentage = 250 Density = 50 Molecular weight/Formula Weight = 25 Solution: Apply Formula: Molarity = [(% x d) / MW] x 10 Molarity = 5000 Thanks for your support, and please visit nitrio.com for more apps for your iOS devices. ## Key features - Molarity calculation for acid/base solutions - Preparation instructions for specified molarity - Uses dilution formula (M1V1=M2V2) - Calculated results are copyable - Includes molarity formula and explanation ## Recent user reviews (2 of 2) All indexed reviews: https://appshunter.io/ios/app/acid-and-base-molarity-calc/id1352167174/reviews.md ### 1/5 — Dangerous *2019-11-28* I would love to know where you get your stock concentration from. ### 1/5 — A waste of space and money *2019-03-05* 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... ## Frequently asked questions about Acid and Base Molarity Calc ### What is Acid and Base Molarity Calc used for?
