Question

What is the concentration of a solution made by diluting 45 mL of 6.0 M HCl to a final volume of 750 mL?

Answer 1

Use the equation concentration 1 * volume 1 = concentration 2 * volume 2 to solve for your final concentration.

C₁V₁ = C₂V₂

C₁ = 6.0 M V₁ = 45 mL V₂ = 750 mL

C₂ = C₁V₁ / V₂ = (6.0 M * 45 mL) / (750 mL) = 0.36 M

The final concentration of the solution formed is 0.36 M HCl
