The new concentration of the solution of KCl which is diluted to a new volume of 1.0 L is 0.28 M KCI.
What is concentration?
Concentration is the abundance of substance or constituent divided by the volume of the mixture.
By the dilution formula
C₁V₁ = C₂V₂
C₂ = C₁V₁/V₂
The concentration is 1.6 M
The volume of KCl is 0.175
The new volume v2 is 1.0 l
Putting the values in the equation
C₂ = 1.6 × 0.175 / 1.0
C₂ = 0.28
Thus, the correct option is b. 0.28 M KCI.
