Question

If 220 mL of a 12.0 M HCl solution is diluted to 1000 mL, what will be the concentration of the new solution?

Answer 1

2.64 M

Step-by-step explanation:

Use the dilution equation M1V1 = M2V2, where:

M1 = 12.0 M HCl

V1 = 220 mL HCl

M2 = ?

V2 = 1000 mL HCl

(12.0 M HCl)(220 mL HCl) = M2(1000 mL HCl)

M2 = 2.64 M HCl
