What volume of 70% sulfuric acid solution (po = 1.622 g / l) should be taken to prepare

What volume of 70% sulfuric acid solution (po = 1.622 g / l) should be taken to prepare 25 ml of 2M sulfuric acid solution. with an explanation if possible.

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 required to hang and dissolve in water 0.025 x 2 = 0.05 mol of acid.

Let’s calculate the required weight of the acid.

To do this, we multiply the molar weight of the acid by the chemical amount of the substance.

M H2SO4 = 2 + 32 + 16 x 4 = 98 grams / mol;

m H2SO4 = 98 x 0.05 = 4.9 grams;

Find the required volume of acid.

V H2SO4 = 4.9 / 1.622 / 0.7 = 4.316 ml.
