How to make 10 percentage dilution?
take 1 ml, add 9 ml water.
How would a scientist make 500 ml of a 2 to 5 dilution of concentrate?
The wording is important here. If it is a 2 *in* 5 dilution, then the scientist would need 200 ml of concentrate. The best way would be to take a graduated cylinder, put about 200 ml of solvent into the cylinder. Then put in the 200 ml of concentrate. Then add enough additional solvent to make a total of 500 ml. Mix, then pour it into a labeled and dated bottle, and screw on the lid. If it is a 2 *to* 5 dilution, then you need 2/7ths concentrate, and 5/7ths solvent. One seventh of 500 ml is about 71.43, so you would need 142.86 ml of concentrate, and fill the rest with solvent until the total is 500 ml.
I have to prepare a 1 to 10 dilution and have a 2ml culture suspension and want to prepare a 1 to 10 dilution of the entire culture.?
Add 2 mL of culture to 20 mL of buffer. 2/20 = 1/10
How do you convert 0.1 N HCl to 0.01 N HCl?
To convert 0.1 N HCl to 0.01 N HCl, you can perform a dilution. For example, mix 10 mL of the 0.1 N HCl solution with 90 mL of distilled water to achieve a total volume of 100 mL, resulting in a 0.01 N HCl solution. The dilution factor here is 10, as you are reducing the concentration by a factor of ten.
How much is 25 centiliters?
250 ml
To prepare 300 ml of a 115 dilution from a 13 dilution you need to add ml of the 13 dilution to ml of diluent?
33,4ml
How to make 10 percentage dilution?
take 1 ml, add 9 ml water.
How much water to add to make a 500 dilution?
To make a 500 dilution, add 1 part of the substance you are diluting to 499 parts of water. For example, if you have 1 mL of the substance, you would add 499 mL of water to make a total volume of 500 mL for the dilution.
What is dilution factor for 10 g of soil in 250 ml of water?
1 in 25. (10/250)
If 31.2 mL of water is added to 0.8 mL of drug A what is the dilution ratio?
32
How do you make a 7.6 fold dilution?
measure 1 ml of the original solution and add 6.6 ml of distilled water.
When 0.25ml is diluted to 20ml the resulting dilution is?
When 0.25 ml is diluted to a final volume of 20 ml, the resulting dilution can be calculated as the ratio of the original volume to the final volume. This is calculated as 0.25 ml / 20 ml, which simplifies to a dilution factor of 1:80. Therefore, the resulting dilution is 1:80.
What dilution factor is 0.5 ml in 7.5 ml of diluent?
The dilution factor is 1:15. This is calculated as the total volume (7.5 ml) divided by the volume of the sample (0.5 ml).
What dilution to make 50percent acetone control?
To make a 50% acetone control, you can mix equal parts of acetone and water. For example, if you start with 10 ml of acetone, you would add 10 ml of water to make a 50% acetone solution.
What will be the final volume of a solution prepared by diluting 25 mL of 8.25 M sodium hydroxide to a concentration of 2.40?
The final volume of the solution will be 68.18 mL. This can be calculated using the formula for dilution, which is M1V1 = M2V2. Solving for V2 (final volume) gives V2 = (M1V1) / M2 = (8.25 M * 25 mL) / 2.40 M = 68.18 mL.
If you have 0.05 ml of an undiluted culture at a concentration of 3.6x10 6 CFU ml You then add 4.95 ml sterile diluent What is the dilution factor and what is the final concentration of cells?
The dilution factor is 1:100, as you're adding 4.95 ml to the original 0.05 ml. The final concentration is calculated by multiplying the original concentration by the dilution factor, resulting in a final concentration of 3.6x10^4 CFU/ml.
What would be the dilution if 96 mL of diluent is added to 4 ml of a bacterial suspension?
100
