## Question:

What is the molarity of a 40.0% by mass hydrochloric acid solution? The density of the solution is 1.1980 g/mL.

a) 18.3 M

b) 13.1 M

c) 0.0479 M

d) 0.400 M

e) 13.9 M

## The Concentration of a Solution:

In quantitative analysis, the identity of the solute in the solution is not the only important thing. It is also important to express the amount of the solute per amount of the solvent or solution so that this value can be used in different calculations including the calculation of the concentration of the analyte solution.
