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.

How many milliliters would you need to prepare 60.0 mL of 0.200 M HNO3 from a stock solution of 4.00 M HNO3?
Calculate the volume of stock solution nitric acid of concentration 4.00 M which is required to prepare 60.0 mL of nitric acid of concentration 0.200 M. ∴The volume of stock solution of nitric acid required is 3 mL.
What is stock solution preparation?
A stock solution is prepared by weighing out an appropriate portion of a pure solid or by measuring out an appropriate volume of a pure liquid, placing it in a suitable flask, and diluting to a known volume. Exactly how one measure's the reagent depends on the desired concentration unit.
How do you make HNO3 solution?
1L contains 15.6 moles, therefore 1 mole is contained within = 1L / 15.6 moles. Add 64.1mL, or 90.4g, of SEASTAR™'s Nitric Acid to water up to 1L to make a 1 Molar Solution of Nitric Acid.
How do you calculate m1v1 m2v2?
1:403:15Dilution m1v1=m2v2 - YouTubeYouTubeStart of suggested clipEnd of suggested clip1 is equal to m2 v2. Over m1 now normally when we're dealing with molarity calculations we want ourMore1 is equal to m2 v2. Over m1 now normally when we're dealing with molarity calculations we want our volume to be in liters. But in this m1 v1 equals m2 v2 type calculations.
How do I calculate molarity?
As mass / volume = molarity * molar mass , then mass / (volume * molar mass) = molarity . Substitute the known values to calculate the molarity: molarity = 5 / (1.2 * 36.46) = 0.114 mol/l = 0.114 M . You can also use this molarity calculator to find the mass concentration or molar mass.
How do you calculate stock solutions?
Strategy:Calculate the number of moles of glucose contained in the indicated volume of dilute solution by multiplying the volume of the solution by its molarity.To determine the volume of stock solution needed, divide the number of moles of glucose by the molarity of the stock solution.
Why do we prepare stock solution?
Stock solutions are used to save preparation time, conserve materials, reduce storage space, and improve the accuracy with which working lower concentration solutions are prepared.
How do you prepare different concentrations from a stock solution?
You can first prepare 0.5% solution (0.5 g per 100 ml) and for 0.25, 0.1, 0.025 and 0.05%, respectively, dilute to half, one fifth, one twentieth and one tenth. For example, add 9 ml water to 1 ml of the stock solution, to 10 times dilute and obtain a concentration of 0.05%.
How do you find the molarity of HNO3?
Knowing that the solution is 70 wt % would then allow the number of grams of HNO3 to be calculated: (0.700)(1413g) = 989.1 grams HNO3 per liter. Dividing the grams of HNO3 by the molecular weight of HNO3 (63.01 g/mole) gives the number of moles of HNO3 / L or Molarity, which is 15.7 M.
How is 70 HNO3 prepared?
One molar is the molarity of a solution where one gram of solute is dissolved in a litre of solution. 2M HNO3 indicates2 moles of HNO3 in 1000mL of solution. = (1×1) + (1×14) + (3×16) = 63 grams. 70% weight by weight means 70g HNO3 is present in 100g of solution.
How do you make a 5% HNO3 solution?
The volume of 7.14 g of concentrated HNO3 can be obtained from the density V = 7.14 g / 1.42 = 5.03 mL. If you then measure 5.03 mL of the concentrated HNO3 and dilute to 100 mL with water, you would have the required 5% solution.
How to tell if HNO3 is a buffer?
HOW CAN U TELL IF HNO3 +KNO3 IS A BUFFER SOLUTION A buffer solution must contain a weak acid and its conjugate base OR a weak base and its conjugate acid. HNO3 is a strong base and KNO3 is the salt of a strong base (KOH) and a
What is the difference between solution A and B?
A is a solution of trioxonitrate (v) acid, HNO3, of unknown concentration. B is standard solution of sodium hydroxide containing 4.00g per dm3 of solution. 25cm3 portions solution B required an average of 24.00cm3 of solution A for
What is solution A?

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.
