0.1 % Triton X-100 is a 1 in 1000 dilution of 100% Triton X-100 (available for purchase). For example, add 1ml 100% Trition to 999ml water to yield 0.1% Triton. I usually keep a stock of 10% triton on hand to make various buffers.
take 1 ml, add 9 ml water.
1 part of solution A plus 99 parts solution B
HPUS is: The Homœopathic Pharmacopœia of the United States 2X means 1:100 dilution. In other words 1%. Normally homeopathic dilutions are much more. 12X or 600X.
If one "whole" is one, then one hundred hundredths make a whole.Think about it this way: One hundredth is 1/100. To get a fraction that equals one, you have to make the top number (numerator) and bottom number (denominator) the same. So, what can you do to get the top number to equal 100 with 1/100? Multiply it by 100 (which is the same as 100/1)!1/100 * 100/1 = 100/100 = 1
2 times dilution from 100% acetone
An 8-fold dilution means you are making your solution 1/8 less concentrated. So, if you want to make 100 ml of a solution diluted 8 fold you would do as follows: 1/8=.125 100*.125= 12.5 Mix 12.5 mL of your concentrated solution with 87.5 mL of your solvent (water etc..) to bring the final volume to 100 mL. If you wanted to perform a ten fold dilution you would simply mix 10 mL of your concentrated solution with 90 mL of your solvent. 1/10=.1 100*.1=10
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.
110
You add 9.09ml of stock solution to a volumetric and make it up to 1 litre to get a 110 dilution
Realistically? None. Homeopathic medications are heavily diluted. The quinine dilution is a 3x (or approximately 1.5 c) dilution. So for the sake of easy math lets say it's an even 2c dilution. That means the quinine is diluted 1 part quinine in 100 parts dilution (like water) and part of that dilution is diluted in another 1:100 parts of dilution (more water). so...what's that work out to? One molecule of quinine per 10,000 molecules of water?
To make a 1 to 5 dilution you mix 1 part of your substance with 4 parts water. ie: Mix 1 tablespoon of creamer with 4 tables spoons of coffee, and the coffee is 1/5 creamer now.
You add 99 L to 1.0 L stock: concentrations are 100 times less.

0.1 % Triton X-100 is a 1 in 1000 dilution of 100% Triton X-100 (available for purchase). For example, add 1ml 100% Trition to 999ml water to yield 0.1% Triton. I usually keep a stock of 10% triton on hand to make various buffers.
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.
You dilute it 1:10, then you take 1 part of that solution and mix it with 9 parts of the diluent. That will make the 1:100 dilution you need, incl. prevention of pipette inaccuracy.
