Answer:

0.1 M

Explanation:

The following data were obtained from the question:

Initial volume (V1) = 100 mL

Initial concentration (C1) = 0.5 M

Final volume (V2) = 500 mL

Final concentration (C2) =?

Using the dilution formula C1V1 = C2V2, the new concentration of the solution can be obtained as follow:

C1V1 = C2V2

0.5 × 100 = C2 × 500

50 = C2 × 500

Divide both side by 500

C2 = 50/500

C2 = 0.1 M

Therefore, the new concentration of the solution is 0.1 M

The new concentration of the solution of KBr that was diluted to 500mL is 0.1M

HOW TO CALCULATE CONCENTRATION:

  • The concentration of solution that was diluted can be calculated using the formula as follows:

  • C1V1 = C2V2

Where:

  1. C1 = original concentration (M)
  2. C2 = diluted concentration (M)
  3. V1 = original volume (mL)
  4. V2 = diluted volume (mL)

  • According to this question, 100.0 mL of a 0.500 M solution of KBr is diluted to 500.0 mL. The new concentration can be calculated as follows:

  • 0.500 × 100 = C2 × 500

  • 50 = 500C2

  • C2 = 50 ÷ 500

  • C2 = 0.1M

  • Therefore, the new concentration of the solution of KBr that was diluted to 500mL is 0.1M.
