Question

to what volume must 1.0 l of a 6.0 m solution of hcl be diluted in order to prepare a 0.2 m solution? select one: a. 30 l b. 20 l c. 10 l d. 40 l

Answer 1

A

Step-by-step explanation:

To determine the volume required to dilute a 1.0 L solution of 6.0 M HCl to a 0.2 M solution, we can use the equation for dilution:

M1V1 = M2V2

Where:

M1 = Initial concentration of the solution (6.0 M)

V1 = Initial volume of the solution (1.0 L)

M2 = Final concentration of the solution (0.2 M)

V2 = Final volume of the solution (unknown)

Rearranging the equation, we have:

V2 = (M1/M2) * V1

Plugging in the values:

V2 = (6.0 M / 0.2 M) * 1.0 L

V2 = 30 L

Therefore, the volume required to dilute the 1.0 L solution of 6.0 M HCl to a 0.2 M solution is 30 liters (option a).
