Calculate the molar concentration of a solution of sulfuric acid h2so4 with a mass fraction

Calculate the molar concentration of a solution of sulfuric acid h2so4 with a mass fraction of 10%, the density of the solution is 1.07 g / ml.

Find the molar mass of sulfuric acid:

M H2SO4 = 1 x 2 + 32 + 16 x 4 = 98 grams / mol;

One liter of solution weighs 1000 x 1.07 = 1,070 grams.

Let’s find the molar amount of sulfuric acid in this mass of the solution.

Sulfuric acid mass:

m H2SO4 = 1,070 x 10% = 107 grams;

Amount of substance:

N H2SO4 = 107/98 = 1.092 mol;

This amount of substance is contained in one liter of solution. This is the equal molar concentration of sulfuric acid:

With H2SO4 = 1.092 mol / liter;
