Question

1.00 mL of a 250.0 µM solution of KCl is diluted to 50.0 mL. What is concentration of this solution?

Answer 1

Answer:

5.00 µM

Explanation:

Given data

• Initial concentration (C₁): 250.0 µM

• Initial volume (V₁): 1.00 mL

• Final concentration (C₂): ?

• Final volume (V₂): 50.0 mL

We can find the final concentration using the dilution rule.

C₁ × V₁ = C₂ × V₂

C₂ = C₁ × V₁ / V₂

C₂ = 250.0 µM × 1.00 mL / 50.0 mL

C₂ = 5.00 µM

The concentration of the diluted solution is 5.00 µM.
