The volume of water needed to dilute the solution to obtain a 0.25 M NaCl solution is 75 mL

Data obtained from the question

  • Volume of stock solution (V₁) = 25 mL
  • Molarity of stock solution (M₁) = 1 M
  • Molarity of diluted solution (M₂) = 0.250 M
  • Volume of water =?

How to determine the volume of diluted solution

  • Volume of stock solution (V₁) = 25 mL
  • Molarity of stock solution (M₁) = 1 M
  • Molarity of diluted solution (M₂) = 0.250 M
  • Volume of diluted solution (V₂) =?

M₁V₁ = M₂V₂

1 × 25 = 0.250 × V₂

25 = 0.25 × V₂

Divide both side by 0.25

V₂ = 25 / 0.25

V₂ = 100 mL

How to determine the volume of water

  • Volume of stock solution (V₁) = 25 mL
  • Volume of diluted solution (V₂) = 100 mL
  • Volume of water =?

Volume of water = V₂ – V₁

Volume of water = 100 – 25

Volume of water = 75 mL
