Question

A solution originally has a concentration of 1.3 x 10-4 m. that solution is diluted by taking 2.0 ml of it and diluting to a volume of 10.00 ml with a volumetric flask. what is the concentration of the diluted solution?

Answer 1

The concentration of the diluted solution is 2.6 x 10-5 M.

Step-by-step explanation:

To calculate the concentration of the diluted solution, we can use the dilution equation:

M1V1 = M2V2

Where M1 is the initial concentration, V1 is the initial volume, M2 is the final concentration, and V2 is the final volume.

In this case, the initial concentration (M1) is 1.3 x 10-4 M, the initial volume (V1) is 2.0 mL, and the final volume (V2) is 10.00 mL.

Plugging in these values, we can solve for the final concentration (M2):

(1.3 x 10-4 M)(2.0 mL) = (M2)(10.00 mL)

M2 = (1.3 x 10-4 M)(2.0 mL) / (10.00 mL) = 2.6 x 10-5 M
