Given, 0.392 m Perchloric acid
Total volume of dilute solution 50.0mL
To solve this use the formula for dilution calculations, which is C1V1 = C2V2,
where the stock solution's concentration is C1,
for example.
The volume you must remove from the stock solution is V1.
C2 is the concentration of the target solution
V2 is the concentration of the target solution
Step1 Starting with this formula, we rearrange the variables to isolate V1 in order to solve for it, as it is the volume we are adding to the solution to get the desired concentration and volume
V1 = (C2V2) / C2
Step 2 Plug in the values and solve
V1 = (0.392 M • 0.005 L) / 6 (Note 50 mL is converted to 0.05 L in order to have consistent units as M which is mol / L)
=0.0003266 L or 0.326 mL
