Question

What volume of 0.0641 M HClO4 solution would you make 250 mL of 0.025 M solution by dilution with water.

Answer 1

97ml of 0.0641M HClO₄

Step-by-step explanation:

Using the dilution equation

(Molarity of conc.)(Volume of conc.) = (Molarity Dilu'd)(Vol Dilu'd)

=> M₁V₁ = M₂V₂ => V₁ = M₂V₂ / V₁

=> V₁ = (0.025M)(250ml)/(0.0641M) = 97ml of the 0.0641M HClO₄
