Question

Problem 32

Answer 1

Given information

The mass percent of   in concentrated solution is .

The density of concentrated solution is    .

The molarity of final solution is    .

The volume of final solution is   .

Step-by-step explanation

Step 1.

The dilution formula can be expressed as:

                                Equation 1

Where,

•    is the molarity of concentrated solution.

•    is the volume of concentrated solution.

•    is the molarity of final solution.

•    is the final volume of solution.

The molarity of the concentrated solution is calculated by the formula,

(This is considered as equation 2)

Where,

•    is the density of concentrated solution.

• is the molar mass of hydrochloric acid.

• is the mass percent of hydrochloric acid.
