Answer:
C₁ = 0.558 M
Explanation:
Given data:
Volume of concentrated solution = V₁ = 25 mL
Molarity of concentrated solution =C₁ = ?
Volume of diluted solution = V₂ = 50mL + 25 mL = 75 mL
Molarity of diluted solution = C₂ = 0.186 M
Solution:
Formula:
C₁V₁ = C₂V₂
Volume of concentrated solution = V₁
Molarity of concentrated solution =C₁
Volume of diluted solution = V₂
Molarity of diluted solution = C₂
Now we will put the values in formula:
C₁V₁ = C₂V₂
C₁ × 25 mL = 0.186 M ×75 mL
C₁ × 25 mL = 13.95 M.mL
C₁ = 13.95 M.mL/25 mL
C₁ = 0.558 M
