The mass percentage of hydrochloric acid within a solution is 22.00%. Given that the density of this solution is 1.110 g/mL, find the molarity of the solution.

The molarity of the solution is 6.67 M.

From the question given above, the following data were obtained:

Mass percent of HCl = 22%

Density of solution = 1.110 g/mL

Percentage by mass of HCl = 22%

Mass of HCl =

NOTE: Assume the mass of the solution to be 1 g.

Molar mass of HCl = 1 + 35.5

= 36.5 g/mol

Mass of HCl = 0.22 g

Density of solution = 1.110 g/mL

Mass of solution = 1 g

Cross multiply

1.110 × Volume = 1

Divide both side by 1.110

Volume = 0.9 mL

Divide by 1000 to express in litres (L)

Mole of HCl = 0.006 mole

Volume of solution = 0.0009 L

Therefore, the molarity of the solution is 6.67 M.
