If 30.0 mL of a 12.0 M hydrochloric acid (HCI) stock solution is diluted to a volume of 500.0 mL,
what is the molarity of the dilute solution?

Respuesta :

Answer:

The concentration of dilute solution is 0.72M

Explanation:

According to the given question

V1=30 ml

 S1 = 12 M

 V2= 500 ml

then S2 =?

  we all know that V1S1=V2S2

                           or  S2= V1S1÷V2

                            or  S2 = 30×12÷500

                             or  S2= 360÷500

                             or  S2  =0.72 M.

The concentration of dilute solution is 0.72 M
