175 ml of a 1.6 m solution of KCl is diluted to a new volume of 1.0 L. The new concentration of the solution is 0.28 m KCl.
Hence, Option (B) is correct answer.
What is Concentration ?
Concentration is defined as the measure of how much substance there is mixed with another substance.
How to find the concentration ?
To find the concentration use the dilution formula
C₁V₁ = C₂V₂
where,
C₁ = Concentration of starting solution
C₂ = Concentration of final solution
V₁ = Volume of the starting solution
V₂ = Volume of the final solution
Now put the values in above formula we get
C₁V₁ = C₂V₂
1.6 × 0.175 = C₂ × 1.0
0.28 = C₂ × 1.0
C₂ = 0.28
Thus from the above conclusion we can say that 175 ml of a 1.6 m solution of KCl is diluted to a new volume of 1.0 L. The new concentration of the solution is 0.28 m KCl.
Hence, Option (B) is correct answer.
