Concentrated nitric acid is 16M. What volume of nitric acid must be diluted with distilled water to prepare 5L of 0.1M nitric acid?

To find the volume of concentrated nitric acid that needs to be diluted, we can use the formula:

C1V1 = C2V2

Where:
C1 = concentration of the concentrated nitric acid
V1 = volume of the concentrated nitric acid to be diluted
C2 = concentration of the diluted nitric acid
V2 = final volume of the diluted nitric acid solution

Given:
C1 = 16M
V1 = ?
C2 = 0.1M
V2 = 5L

Substituting the given values into the formula:

16M × V1 = 0.1M × 5L

Simplifying the equation:

16V1 = 0.5

Now, we can solve for V1:

V1 = 0.5 / 16

V1 ≈ 0.03125 L

Therefore, approximately 0.03125 liters (or 31.25 milliliters) of concentrated nitric acid should be diluted with distilled water to prepare 5 liters of 0.1M nitric acid solution.
