Answer:

To calculate the volume of the solution that contains 23 grams of nitric acid we first need to determine the mass of the solution.

Given:

Mass of concentrated nitric acid (HNO3) = 23 grams

Percentage concentration of nitric acid = 69%

Density of concentrated nitric acid = 1.41 g/mL

First we need to find the mass of the solution. Since the mass percentage of nitric acid is given we can use the following equation:

Mass of solution = Mass of nitric acid / (Percentage concentration/100)

Therefore the mass of the solution can be calculated as follows:

Mass of solution = 23 grams / (69/100)

= 23 grams / 0.69

≈ 33.33 grams

Next we can calculate the volume of the solution using the density of concentrated nitric acid:

Volume of solution = Mass of solution / Density of solution

Using the given density value:

Volume of solution = 33.33 grams / 1.41 g/mL

≈ 23.66 mL

Therefore the volume of the solution containing 23 grams of nitric acid is approximately 23.66 mL.
