Answer to Question #181165 in General Chemistry for Ally

Question

If 545 ml of a 4.50 M solution of HCl was used to prepare a 1.45 L solution of dilute HCl, calculate the molar concentration of the dilute solution.

Answer 1

M₁ = 4.50M , V₁ = 545ml = 0.545L

M₂ = ? , V₂ = 1.45L

M₁V₁ = M₂V₂

4.50×0.545 = M₂ × 1.45

M₂ = 1.69M
