Question

Distilled vinegar contains a solution of acetic acid (CH3CO2H) in H2O. What is the concentration of the solution that results from diluting 500 ml of 0.839 M vinegar solution to 2.5 L?

Answer 1

0.168M

Step-by-step explanation:

We obtained the following information from the question:

C1 = 0.839 M

V1 = 500mL = 500/1000 = 0.5L

C2 =?

V2 = 2.5L

Using the dilution formula, we can obtain the concentration of the diluted solution as follows:

C1V1 = C2V2

0.839 x 0.5 = C2 x 2.5

Divide both side by 2.5

C2 = (0.839 x 0.5) /2.5

C2 = 0.168M the concentration of the diluted solution is 0.168M
