The volume of stock solution of 5M H₂SO₄ needed to prepare 100mL of 0.25M H₂SO₄ is 5mL.
How do we calculate the volume?
Volume of stock solution to prepare any dilute solution will be calculated by using the following formula:
M₁V₁ = M₂V₂, where
M₁ & V₁ is the molarity and volume of stock solution, and
M₂ & V₂ is the molarity and volume of final prepared solution.
On putting values from the question to the above formula and calculate for the value of V₁ as:
V₁ = (0.25)(100) / (5)
V₁ = 5 mL
Hence required volume is 5mL.
