Question

Concentrated aqueous perchloric acid is 70.5 wt% HClO4 and has a concentration of 11.7 M. Calculate the volume of concentrated perchloric acid that should be diluted to 1.90 L to form a 5.00 M HClO4 solution.

Answer 1

0.812 L

Step-by-step explanation:

As this is a dilution process problem, we can solve it by using the C₁V₁ = C₂V₂ formula, where in this case:

• C₁ = 11.7 M

• V₁ = ?

• C₂ = 5.00 M

• V₂ = 1.90 L

We input the data:

• 11.7 M * V₁ = 5.00 M * 1.90 L

And solve for V₁:

• V₁ = 0.812 L

This means that 0.812 L of concentrated perchloric acid should be diluted to a final volume of 1.90 L.
