Question

The concentration of dye in Solution A is 25.527 M. You have 13 mL of water at your disposal to make the dilutions. The solution is diluted twice, to make Solutions B and C. In the first dilution, 8 parts of Solution A is diluted with 12 parts water to make Solution B. In the second dilution, 8 parts of Solution B is diluted with 4 parts water to make Solution C. What is the concentration of dye in Solution C

Answer 1

Answer:

 38825.472 M

Explanation:

Using

C1V1=C2V2

To make solution B,

C1 = 25.527 M, V1 = 13 mL

C2 = 25.527 x 8 = 204.216 M

V2 = 13 X 12 = 156 mL

To make solution C'

C1 = 8 X 202.216 M = 1617.728

V1 = 8 X 156mL = 1248 mL

V2 = 4 X 13 = 52 mL

C2 = C1V1 / V2

    =1617.728 X 1248 / 52

 =38825.472 M
