Question

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?

Answer 1

The concentration of dilute solution is 0.72M

Step-by-step 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
