Question

175 ml of a 1.6 m solution of kcl is diluted to a new volume of 1.0 l. what is the new concentration of the solution?

Answer 1

The new concentration of the KCl solution after mixing 1 L new volume is 0.28 M.

How do we calculate the concentration?

Concentration in terms of molarity will be calculated by using the below equation as:

M₁V₁ = M₂V₂, where

M₁ = molarity of old KCl solution = 1.6 M

V₁ = volume of old KCl solution = 175 mL = 0.175 L

M₂ = molarity of new KCl solution = ?

V₂ = volume of new KCl solution = 1 L

On putting all these values on the above equation, we get

M₂ = (1.6)(0.175) / (1) = 0.28 M

Hence resultant concentration is 0.28 M.
