What volume of 5M KOH solution is required to prepare a 0.6M potassium hydroxide solution

What volume of 5M KOH solution is required to prepare a 0.6M potassium hydroxide solution with a volume of 250 ml?

Determine the required amount of a substance for preparing a solution.

To do this, multiply the volume of the solution by its molar concentration.

In order to prepare such a solution, it is necessary to weigh and dissolve 0.25 x 5 = 1.25 mol of alkali in water.

Let’s calculate the required weight of alkali.

To do this, we multiply the molar mass of the alkali by the chemical amount of the substance.

M KOH = 39 + 16 + 1 = 56 grams / mol;

m KON = 1.25 x 56 = 70 grams;
