How do you calculate stock solutions?

Strategy:

  1. 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.
  2. To determine the volume of stock solution needed, divide the number of moles of glucose by the molarity of the stock solution.

How do you prepare a standard stock 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 do you make a 10% stock solution?

How to make 10% SDS stock solution

  1. Weigh out 10 g SDS and add to a 100 mL Duran bottle.
  2. Measure out 80 mL of distilled water and add to the Duran bottle.
  3. Add a magnetic flea and place on a magnetic stirring plate to mix the solution.

How do you make a 5% stock solution?

Dilute the compound with the necessary amount of solvents. Using a graduated cylinder (a measuring device used specifically for volume), measure out the desired amount of liquid. Mix with powdered compound until dissolved. For example: Mix 500 mL of water and 25 g of NaCl to make a 5% solution.

How do you prepare stock solution in ppm?

You may prepare the 1ppm stock solution first by dissolving 1 mg of solute into 1000 mL of the solvent. After that, you can prepare the solution of any desired concentration using the formula, M1V1=M2V2. I hope this answer will help you.

What is meant by stock solution?

Definition of stock solution : a concentrated solution (as of developer) that usually is diluted with water before use in photography.

How do I make a 10 mg/ml stock solution?

To prepare a concentration of 10 µg/ml, pipette out 10 µl of the drug in a test tube using a micropipette. Then dilute it with 990 µl (making a total volume of 1 ml) of the solvent (ethanol, methanol, water etc) you are going to use in your experiment. Similarly, do for 20 µg/ml.

How do you make a 4% solution?

4% NaOH →Mean 4 grams of NaOH is dissolved in 100 ml of the solution. 4g ——> 100 ml? ——–> 50 ml The Weight in grams of NaOH needed to prepare 4% NaOH is = (4 x 50)/100 = 2 g. So, 2 grams of NaOH is dissolved in little water and the volume made up to 50 ml.

How do I make a 1000 ppm stock solution?

Whatever be the density of the solution, weigh 0.1g of the substance in beaker and transfer the content to 100mL standard measring flask using your medium or solvent. Make up to the mark. It will result 1000 ppm of the solution. From this stock you can dilute to desired ppm of the solution.

What is a 10X stock solution?

Form example, a 10X stock solution is one that contains ten times the concentration of all solutes relative to a working solution, which is considered to be a 1X solution. • Therefore, you need to dilute a 10X by a factor of ten to obtain your final working solution.

What is a 1000x stock solution?

1000x refers to the stock concentration respect to the concentration in the working solution, ie 1000 times higher concentration. If the final concentration of the chemokines you need is 20ug/mL, 1000x would be 20,000 ug/mL or 20 mg/mL.
