Refer below to the formula of dilution:
C1V1 = C2V2
Sample problem:
How much water and how much 12 M HCl must be used to prepare 500 ml of a 1 M HCl solution? # Determine the volume of 12 M to be used using the dilution formula (12) (volume of 12 M) = (1) (500) volume of 12 M = (1) (500) / 12 = 41.7 ml 12 M # Determine the volume of water to add to it Total volume after dilution = volume of 12 M + volume of water added 500 = 41.7 + volume of water added 500 - 41.7 = volume of water = 458.3 ml of water to be added to the 41.7 ml of 12 M

(12) (volume of 12 M) = (1) (500) volume of 12 M = (1) (500) / 12 = 41.7 ml 12 M
Total volume after dilution = volume of 12 M + volume of water added 500 = 41.7 + volume of water added 500 - 41.7 = volume of water = 458.3 ml of water to be added to the 41.7 ml of 12 M
A dilution ratio is a shorthand method to represent a dilution performed using integer ratios of solvent. For example let's say you have 100mL of an aqueous 1M solution. Transfer 25mL of this solution to a 100mL volumetric flask, and dilute with water to the 100mL mark. This solution is now 0.25M, a 1:4 dilution. I have seen this mistakenly reported as a 1:3 dilution, adding the two integers together to get the new solution volume. Important to note is that the second value in the dilution ratio representation (the 'four' in the 'one to four') is the TOTAL amount of solvent, not the added amount, which would be 3.
to find the concentration of a substance the formula is:
c= n /v ( concentration equals moles over volume
Use V1*c1 = V2*c2 with similar units on each side.
For example mass of a solute in a known volume or mass of a solvent (concentration).
A solution is a mixture and hasn't a chemical formula.
Dilution hasn't a chemical equation.
Concentration is the mass of a component/volume (or total weight) ratio.

Direct dilution using the exact dose needed to get a specific response so that the dose is a stochastic variable, showing tolerance distribution. Double dilution is when the isotopic composition of two blends is the same.
how do you calculate pKa
grams and to calculate use a pan balance
to calculate viscosity index
1:2 dilutions

Homeopathic preparations of Thuja include pills, granules, and liquid dilutions, in potencies ranging from 3X to 50M.
Ledum taken in the standard homeopathic dilutions has not been reported to cause side effects.

Dilution is necessary for getting isolated colonies, from which pure culture shall be obtained for further study.
These can be used fresh or dried to make an infusion (tea) or a decoction. For homeopathic remedies, the dried plant material is ground finely then prepared by extensive dilutions.
We distil raw science from it's more concentrated form, into lower more manageable dilutions so it can be digested by the general public.
Placing a question mark at the end of a phrase does not make it a sensible question. Try to use a whole sentence to describe what it is that you want answered.
For homeopathic remedies, the remedy material is finely ground and then prepared by extensive dilutions. In the early days of homeopathy, silica was prepared from powered rock.
