Question

If 2.0 mL of 6.0 MHCl is used to make a 500.0-mL aqueous solution, what is the molarity of the dilute solution? 0.30 M 0.24 M 0.024 M 0.83 M

Answer 1

0.024 M

Explanation:

The molarity of the dilute solution is 0.024 M.

To calculate the molarity of the dilute solution, we can use the following equation:

M1V1 = M2V2

where:

M1 is the molarity of the concentrated solution

V1 is the volume of the concentrated solution

M2 is the molarity of the dilute solution

V2 is the volume of the dilute solution

We know the following values:

M1 = 6.0 M

V1 = 2.0 mL

V2 = 500.0 mL

We can now plug these values into the equation and solve for M2:

(6.0 M)(2.0 mL) = M2(500.0 mL)

M2 = (6.0 M)(2.0 mL) / (500.0 mL)

M2 = 0.024 M

Therefore, the molarity of the dilute solution is 0.024 M.

The answer is 0.024 M.
