Question

To what volume should you dilute 20 mL of a 11 M stock HCl solution to obtain a 0.580 M HCl solution?

Answer 1

use dilution formula

M1*V1 = M2*V2

Here:

M1 is molarity of solution before dilution

M2 is molarity of solution after dilution

V1 is volume of solution before dilution

V2 is volume of solution after dilution

we have:

M1 = 11.0 M

M2 = 0.58 M

V1 = 20.0 mL

we have below equation to be used:

M1*V1 = M2*V2

V2 = (M1 * V1) / M2

V2 = (11*20)/0.58

V2 = 379 mL

Answer: 379 mL
