What volume should you dilute 55 Ml to obtain m HNO3 solution?
To what volume should you dilute 55 mL of a 11 M stock H N O3 solution to obtain a 0.137 M H N O3 solution? You need to dilute the given volume of stock solution to 4.4 L. Molarity (M) represents the concentration of a solution in moles of solute /liters of solution.
How to calculate volume of stock solution for dilution?
Your first step is to calculate the volume of stock solution that is required. MdilutionVdilution = MstockVstock. (1.0 M)(50 ml) = (2.0 M)(x ml) x = [(1.0 M)(50 ml)]/2.0 M. x = 25 ml of stock solution. So to make your solution, you pour 25 ml of stock solution into a 50 ml volumetric flask.
How to calculate dilution using law of Conservation of mass?
Use the law of conservation of mass to perform the calculation for the dilution: As an example, say you need to prepare 50 milliliters of a 1.0 M solution from a 2.0 M stock solution. Your first step is to calculate the volume of stock solution that is required. To make your solution, pour 25 ml of stock solution into a 50 ml volumetric flask.
How do you prepare a 50ml solution of a solution?
As an example, say you need to prepare 50 ml of a 1.0 M solution from a 2.0 M stock solution. Your first step is to calculate the volume of stock solution that is required. So to make your solution, you pour 25 ml of stock solution into a 50 ml volumetric flask. Dilute with solvent to the 50 ml line.

Why do you start with a concentrated solution and then dilute it to make a dilution?
The primary reason you start with a concentrated solution and then dilute it to make a dilution is that it's very difficult—and sometimes impossible—to accurately measure solute to prepare a dilute solution, so there would be a large degree of error in the concentration value.
What is a dilute solution?
A dilution is a solution made by adding more solvent to a more concentrated solution (stock solution), which reduces the concentration of the solute. An example of a dilute solution is tap water, which is mostly water (solvent), with a small amount of dissolved minerals and gasses (solutes).
Can you dilute a solution with too much solvent?
It's a common mistake to add too much solvent when making the dilution. Make sure you pour the concentrated solution into the flask and then dilute it to the volume mark. Do not, for example, mix 250 ml of concentrated solution with 1 liter of solvent to make a 1-liter solution.
