How do you dilute 10 times?
For example, to make a 1:10 dilution of a 1M NaCl solution, you would mix one “part” of the 1M solution with nine “parts” of solvent (probably water), for a total of ten “parts.” Therefore, 1:10 dilution means 1 part + 9 parts of water (or other diluent).

What is meant by 10-fold dilution?
A ten-fold dilution reduces the concentration of a solution or a suspension of virus by a factor of ten that is to one-tenth the original concentration. A series of ten-fold dilutions is described as ten-fold serial dilutions.
How do you calculate a 1/10 serial dilution?
The dilution factor or the dilution is the initial volume divided by the final volume. For example, if you add a 1 mL sample to 9 mL of diluent to get 10 mL of solution, DF=ViVf = 1mL10mL=110 . This is a 1:10 dilution.
What does 10x dilution mean?
Mixing 100 µL of a stock solution with 900 µL of water makes a 1:10 dilution. The final volume of the diluted sample is 1000 µL (1 mL), and the concentration is 1/10 that of the original solution. A 1:10 dilution is also called a 10x dilution.
Why is serial dilution usually performed with a power of 10 dilution?
Objectives of Serial Dilution Serial dilutions are commonly performed to avoid having to pipette very small volumes (1-10 µl) to make a dilution of a solution.
How do you make a 10 fold dilution with the final volume of 10mL?
To do a 10 fold dilution of 1M Stock solution to 100mL, Mix 10mL of 1M stock with 90mL of Diluent. Label the tube as Dilution 1. From Dilution 1 tube take 10mL and mix 90mL of diluent and Label it as Dilution 2.
What does it mean to dilute 10 times?
The idea here is that in a 10 -fold dilution, the volume of the diluted solution is 10 times higher than the volume of the stock solution. This is equivalent to saying that the concentration of the stock solution is 10 times lower than the concentration of the diluted solution.
What does 10X dilution mean?
How much diluent should be used in order to create a 1/10 dilution using a sample volume of 5 ml?
Answer: 1:5 dilution = 1/5 dilution = 1 part sample and 4 parts diluent in a total of 5 parts. If you need 10 ml, final volume, then you need 1/5 of 10 ml = 2 ml sample. To bring this 2 ml sample up to a total volume of 10 ml, you must add 10 ml – 2 ml = 8 ml diluent.
Why is serial dilution usually performed with a power of 10 dilutions?
How to calculate the serial dilution?
Calculate the final dilution ratio in a serial dilution. The total dilution ratio can be determined by multiplying the dilution factor of each step leading up to the final step. This can be mathematically illustrated with the equation D t = D 1 x D 2 x D 3 x … x D n where D t is the total dilution factor and D n is the dilution ratio.
How to solve serial dilutions?
How many grams of dry NaCl should be used to make 100 mL of 15% (W/V) NaCl solution?
How do you perform a 10 fold serial dilution?
Make sure to always research the precautions to use when working with specific chemicals.
What are the advantages and disadvantages of serial dilution?
Serial Dilution-agar Plate Procedure Advantages And Disadvantages Pour plate method is usually the method of choice for counting the number of colony-forming bacteria present in a liquid specimen. In this method, fixed amount of inoculum (generally 1 ml) from a broth/sample is placed in the center of sterile Petri dish using a sterile pipette.
