Question

10 ml of a 0.25M solution is diluted to make exactly 250 ml of solution. What's the concentration of the diluted solution?

Answer 1

0.01 M

Step-by-step explanation:

As this problem deals with a dilution process, we can solve it by using the following formula:

• C₁V₁=C₂V₂

Where subscript 1 stands for the initial concentration and volume, while 2 stands for the final conditions.

That means that in this case:

• C₁ = 0.25 M

• V₁ = 10 mL

• C₂ = ?

• V₂ = 250 mL

We input the given data:

• 0.25 M * 10 mL = C₂ * 250 mL

• C₂ = 0.01 M
