Question

If 2.0 mL of 6.0M HCl is used to make a 500.0-mL aqueous solution, what is the molarity?

Answer 1

Answer:

0.024M

Explanation:

Data obtained from the question include:

C1 = 6M

V1 = 2mL

C2 =?

V2 = 500mL

The molarity of the diluted solution can be obtained as follows:

C1V1 = C2V2

6 x 2 = C2 x 500

Divide both side by 500

C2 = (6 x 2) /500

C2 = 0.024M

The molarity of the diluted solution is 0.024M

Answer 2

Answer:

The molarity is 0.024 mol / L

Explanation:

Molarity = Number of moles / Volume of solution

= (6.0 mol/L x 2.0 x $10^{-3}$ L) / 0.500 L

= 0.024 mol / L
