How can you prepare 250 mL of 0.20 M NaCl using a stock solution of 1.0 M NaCl and water?

How would you prepare 250 mL of 0.20M NaCl using only a solution of 1.0M NaCl and water? Transfer 5.0×10^1 mL of the 1.0 M solution to a 250.0 mL volumetric flask and add enough water to the mark.

How would you prepare 250 mL of a 0.10 M NaCl solution?

The correct answer is d) Dissolve 1.46 g of NaCl in 50 mL of H2O H 2 O and dilute to 250 mL. This is the correct answer because we are preparing 1/4 of a liter of 0.1M solution, meaning that we need 1/4 of 0.1 moles or 1.46g of NaCl.

How would you prepare 500ml of a 0.25 M NaCl solution?

Transcribed image text: To make a total of 500 mL of 0.25 M NaCl, add 125 mL of 1 M NaCl to 375 mL of water. .

How would you prepare 1M solution of NaCl in 250 mL?

1 Expert Answer 0.250 L * (1 mole/ 1 L NaCl) * (54.4 g/ mole NaCl) = 13.6 g NaCl. You would add 13.6 g NaCl to 250 mL of water.

How do you prepare a solid solution?

From solid material Calculate the amount of solute required to prepare the desired solution. Weigh out the amount of solute calculated in step (2) and obtain a volumetric flask of appropriate volume. Add the solute to the volumetric flask. Fill the volumetric flask approximately two thirds full, stopper and mix.

How do you make 100ml of 1M NaCl?

Mass of the solute,W=? So, 5.853g of NaCl are required to make 100ml of a 1M solution. A 1M NaCl solution has 1 mole NaCl per liter.

How you would prepare 250 mL of a 0.707 M NaNO3 solution?

Thus in order to prepare a solution of 250 mL of a 0.707 molar concentration NaNO3 solution we have to dissolve 15.0 g NaNO3 in enough distilled water to make 250 mL solution.

What laboratory equipment do you need to prepare a .250 M stock solution of NaCl?

To make the solution we need to calculate the amount of NaCl to dissolve to make 250 mL of solution. The solution is made by adding 4.38 g NaCl to a 250-mL volumetric flask. About 100 mL of water are added and when all the NaCl dissolves water is added up to the line on the volumetric flask.

How many milliliters of a 5 M solution would be needed to make 250 mL of a 2 M solution?

How many milliliters of a 5 M solution would be needed to make 250 mL of a 2 M solution? Therefore, when 100 mL of a 5M solution is diluted to 250 mL, the resulting solution is 2M.

How many grams of Agno 3 are needed to make 250 mL of a solution that is 0.145 M?

The mass of AgNO3 A g N O 3 needed is 5.95 g.

How do you make a 1M solution?

Molar solutions To prepare a 1 M solution, slowly add 1 formula weight of compound to a clean 1-L volumetric flask half filled with distilled or deionized water. Allow the compound to dissolve completely, swirling the flask gently if necessary.

How do you make a 5M solution of NaCl?

To prepare a 5 M solution: Dissolve 292 g of NaCl in 800 mL of H2O. Adjust the volume to 1 L with H2O. Dispense into aliquots and sterilize by autoclaving. Store the NaCl solution at room temperature.

How to determine the amount of NaCl present in 200ml solution?

Anyways, one will determine the amount of NaCl present in 200ml of 0.3M solution of NaCl: The most direct method would be to add the amount of NaCl present in 200ml of 0.3M solution of NaCl, although such a method will be impractical in laboratories where often large quantities of NaCl is needed.

What is the best way to prepare NaCl?

Try it for free! The most direct method would be to add the amount of NaCl present in 200ml of 0.3M solution of NaCl, although such a method will be impractical in laboratories where often large quantities of NaCl is needed. In these situations, a stock solution of large volumes of 1.0M of NaCl is prepared.

How do you make a 10 mL solution of 2m solution?

To prepare the 10 mL of 2 M solution, you must first transfer about 5 mL of distilled water into your 10 mL volumetric flask. Next, slowly add your 4 mL of stock solution (sulfuric acid). Swirl the flask and then top it up with more distilled water to the 10 mL mark.

How much salt do I need to make 200ml solution?

You only need 0.3M solution so you’ll need 0.3 times that amount. Dissolve that in about 150 ml of water completely then carefully add more water to get exactly 200 ml of solution. You do that because if you add the correct amount of salt to 200ml of
