Question

What is the volume of 18.0 M concentrated HCl solution that must be diluted in order to make 250mL of a 2.00 M HCl solution?

Please help, and I’ll thank you.

Answer 1

The answer to your question is: V1 = 27.8 ml of HCl 18 M

Step-by-step explanation:

Data

HCl = [18M]

HCl Vol = ?

HCl = [ 2M]

HCl vol = 250 ml

Formula

V₁ C₁ = V₂ C₂

V₁ = V₂ C₂ / C₁

Process (substitution)

V₁ = (250)(2) / 18

V₁ = 500 / 18

V1 = 27.8 ml
