Determine the concentration of a solution that started out as 0.1 L of a 0.1 M solution and ended with a final volume of 0.5 L.

C₂ = 0.02 M

Explanation:

Given data:

Initial volume of solution = 0.1 L

Initial molarity = 0.1 M

Final volume = 0.5 L

Final concentration = ?

Solution:

Formula:

C₁V₁ = C₂V₂

C₁ = Initial volume of solution

V₁ = Initial molarity / concentration

C₂ = Final concentration

V₂ = Final volume

Now we will put the values in formula.

C₁V₁ = C₂V₂

0.1 M × 0.1 L =  C₂ × 0.5 L

0.01 M.L = C₂ × 0.5 L

C₂ = 0.01 M.L /  0.5 L

C₂ = 0.02 M
