To prepare 2L of a 5M solution, you should put in 4.6575grams of KMnO4. It is important to make sure that you add them in that order. K should be added first, then Mn.
A water based lubricant. Most recomanded are a saline solution, which has a similar concentration to the levels maintained by the body.

A cell is hypertonic when it has a greater concentration than its environment, but, when a solution is hypertonic, it has a greater concentration than the cell it is being compared to. For example, a 5% salt solution is hypertonic to an onion cell while the onion cell is hypotonic to the solution.The salt concentration of an onion cell must be less than 5% - actually its somewhere between 1.6 and 1.3 percent.This question should not be in genetics, but I don't feel like switching it.
A 5% sucrose solution has 5 grams of sucrose in every 100 grams of solution. As 1mL of water has a mass of 1 gram, you should dissolve 5 grams of sucrose in 95 mL of water.

you should add more of the solute to the solution to make it more concentrated and more of the solvent to the solution to make it diluted.
The hydrogen ion concentration having a PH of 11 is acidic.
Saline solution should always be in given as a concentration of 0.9% sodium chloride (NaCl).
If this is .020m solution, you need 3.81g If this is .20m solution, you need 38.1g If this is 20m solution, you need 3810g
HCl is a strong acid. Therefore, it can be expected to fully dissociate in aqueous solution, yielding one hydrogen ion and one chloride ion per molecule. The concentration of the hydrogen ion should thus be the same as the initial concentration of the HCl. Therefore, a 0.10M HCl solution has an H+ concentration of 0.10M. By the equation pH=-log[H+], the pH of this solution is 1.
The concentration of the diluted solution will be 15(300/1000) = 4.5 %, if the percent is expressed on a weight/volume basis.

The difference in Hydrogen ion concentration between pH12 an pH13 is 10 fold. But, no one should consider a solution with a pH of 12 an "acidic solution". Anything above pH 7 is a basic or alkaline solution.
Chemically and physically speaking:SolventSolutethird part??? I don't know, who else?But maybe in another category and/or an other meaning of the word solution
