take 1 ml, add 9 ml water.
To make a 1 to 100 dilution from a 1 to 10 dilution, first take 1 part of the 1 to 10 dilution and add it to 9 parts of diluent (such as water or buffer). This results in a 1 to 100 dilution because the original 1 to 10 dilution is already diluted, and further diluting it by 10 times achieves the desired concentration. Ensure thorough mixing to achieve uniformity.
Add 2 mL of culture to 20 mL of buffer. 2/20 = 1/10
To make a 1 to 1 dilution, you combine equal volumes of the concentrated solution and a diluent, typically a solvent like water. For example, if you have 10 mL of the concentrated solution, you would add 10 mL of the diluent. Mix thoroughly to ensure a uniform solution. This results in a final volume of 20 mL at half the concentration of the original solution.
10 as a percentage of 2 is 500% but 2 as a percentage of 10 is 20%
It is: 10/40 = 25% as a percentage
To make a 1 to 100 dilution from a 1 to 10 dilution, first take 1 part of the 1 to 10 dilution and add it to 9 parts of diluent (such as water or buffer). This results in a 1 to 100 dilution because the original 1 to 10 dilution is already diluted, and further diluting it by 10 times achieves the desired concentration. Ensure thorough mixing to achieve uniformity.
To prepare a final dilution of 10^-10, you can start with a stock solution at a known concentration. First, create a 10^-1 dilution by mixing 1 part stock solution with 9 parts diluent (e.g., sterile water). Then, take 1 part of this 10^-1 dilution and mix it with 9 parts diluent to create a 10^-2 dilution. Repeat this step until you reach the desired 10^-10 dilution, performing a series of ten 1:10 dilutions.
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.
To find out how many ounces of chemical it would take to make 100 gallons of finished dilution at 0.5%, we can set up a proportion. Since 11 ounces of chemical are used in 10 gallons of water, we can establish the ratio of ounces of chemical to gallons of water as 11:10. By setting up a proportion and solving for x, we find that it would take 110 ounces of chemical to make 100 gallons of finished dilution at 0.5%.
Add one part of the substance you want to dilute to nine parts water. Nine parts water plus one part substance is 10 parts. If you add one part substance to 10 parts water, you get an 11-fold dilution.
To prepare a 10-liter solution of Roundup, you'll need to follow the manufacturer's instructions, which typically specify a dilution rate. For example, if the recommended dilution is 10 mL of Roundup per liter of water, you would need 100 mL of Roundup for a 10-liter solution. Always refer to the product label for the exact dilution ratio specific to the type of Roundup you are using.

In chemistry and biology, the dilution factor is the total number of unit volumes in which the material is dissolved. As I understand it, the dilution refers to the dilution ratio. If you add 1 part of something to 4 parts of something else, the dilution ratio is 1 to 4. The dilution factor counts all the parts and expresses the same thing as 1 out of 5.
It is a mixture of 1 part of the active ingredient (by volume) to 10 parts of the solvent.
