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.
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.
Silver Nitrate is a compound. A compound is formed in such a way that its constituent elements share or transfer electrons in order to become stable. So, the valencies are complete. A compound is stable. Only elements have valence electrons.
Concentrated H2SO4 is 96 %.( In laboratory ) As density of concentrated H2SO4 is 1.84gm/ml we will need this number as well, and as the atomic mass of H2SO4 is 98.08,as it is dibasic for normality it is 49 hence, Calculation=((96/100)(1000)(1.84))/49=36.04 If H2SO4 concentrated is 36.04 M then for make a 1L solution of 1M H2SO4 (36.04)X (x) = 1X(1) x = 1 X(1) / (36.04) x=0.0277gm/ml of water x = 27.7 mL of 36M H2SO4 per liter Hence for 1N H2SO4 dissolve 27.7ml of it to 1000ml of solvent(Water) that means for 0.1 N H2SO4 2.77 ml of it to 1000mL of solvent.
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.
1X PBS might mean 1 in 10 solution 1/10
To prepare 1X TE buffer from 5X TE buffer, you would dilute the 5X TE buffer by mixing 1 part of the 5X buffer with 4 parts of water. For example, mix 1 ml of 5X TE buffer with 4 ml of water to obtain 5 ml of 1X TE buffer.
It is just Phosphate buffered saline.
10X PBS (0.1M PBS, pH 7.4): NaCl --------------------------------------------- 80 g KCl----------------------------------------------- 2g Na2HPO4 (anhydrous) ----------------------- 14.4 g KH2PO4 (anhydrous) ------------------------- 2.4g Distilled water ------------------------------- 1000 ml Mix to dissolve and adjust pH to 7.4 Store this solution at room temperature. Dilute 1:10 with distilled water before use and adjust pH if necessary.
Only use 1X PBS. 10X PBS is made up because it is easier to store and can be diluted when needed. Labs that use PBS often use it in large quantities so making up 10 or 20 liters at a time is usual and making it up as a concentrate is easier to do.
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.

A 1X buffer refers to a buffer solution that is typically used at its full strength, without any dilution. It is commonly used in laboratory settings for various biochemical and molecular biology applications to maintain a stable pH and ionic strength for reactions.
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

To prepare a 3L (3000 mL) TAE solution using 50x TAE buffer, you would need to dilute the 50x buffer by a factor of 50. Therefore, you would take 60 mL of the 50x TAE buffer and add it to 2940 mL of distilled water to achieve a final volume of 3L of 1x TAE solution.
