Question

How many milliliters of a 5.0 M H₂SO₄ stock solution would you need to prepare 103.5 mL of 0.31 M H₂SO₄?

Answer 1

Use dilution equation: moles of solute are constant when diluting: n = M₁V₁ = M₂V₂ where M is molarity of one case and Volume is the volume of the solution in that case.

If concentrate solution is case 1, you are solving for V₁ knowing M₁, V₂, M₂

Good luck!
