The stocks are commonly labeled as X factors such as 10X, 5X, 100X etc. X-factor indicates that the solution is concentrated and must be diluted usually with water to 1X concentration for use.
For eg: - A 100X concentrated solution should be diluted to 100 fold.
to convert 1X to 10X
take one ml of 1x buffer in a measuring cylinder and dilute it to make it 10 ml.
its now 10x buffer.
preparation of 500 ml 1x TAE buffer,50ml of 10x buffer add to 450ml DI.water. to calculate just use MV=MV so 500mL * 1x= 10x * V then solve for V. add the amount of DI water you need to get the volume you calculated above.
Molarity of 1X PBS is 10mM. To prepare 20mM PBS take 16g of NaCl, 0.4 g KCl, 2.88 g Na2HPO4 0.48 g KH2PO4 in 800 ml of distilled H2O. Adjust the pH to 7.4 with HCl. Add H2O to 1 liter.

Solutions that resist change in pH when added to a strong acid or base are known as buffer solutions.
10x to 1x is a 1:10 dilution Therefore, add 1 part buffer, 9 parts DI-water If 100uL is 10uL (1 part buffer) and 90uL (9 parts DI-water) Then, 200ul (100 x 2) is 20uL (1 part buffer) and 180uL (9 parts DI-water)
10x - 1x = 9
I think you mean electrphoresis buffer ( anyway the principle is the same for all sloutions,, simply it is chemistry ) if so , you'll need to take about 25 ml from your 40X buffer and complete them till 1000 ml with distilled water. The calculation can be done as the following N * V = N' * V' so 40X * Z = 1X * 1000 Z is the amount of 40X buffer needed to be diluted to give us 1L of 1X buffer so Z = 1000/40=25 ml
9x + 1x = 10x.
incomplete formula.1x of 20 equals 2 = .10x is 0.1x?=2 ?=20
preparation of 500 ml 1x TAE buffer,50ml of 10x buffer add to 450ml DI.water. to calculate just use MV=MV so 500mL * 1x= 10x * V then solve for V. add the amount of DI water you need to get the volume you calculated above.
This depends on the final volume you intend on making. Say you want to prepare 500 mL of 1X TAE. You will need 10 mL of 50X TAE to prepare 500 mL of 1X TAE.
x+0.1x=110 10x+1x=1100 11x=1100 x=100
10x=80 divide each side by 10 to get x by itself 10/10x=1x 80/10=8 x=8
-11x-1 = -10x-8 -11x+10 = -8+1 -1x = -7 x = 7

Isolate the variable. Get it by itself. 9+11x=89+x 9+11x-1x=89+x-1x Subtraction property of equality 9+10x=89 9+10x-9=89-9 subtraction property of equality 10x=80 x=8 division property of equality.
