Question

Why concentration of the mixture is halved after mixing?

Answer 1

Answer:

For example, if we mix 1.0 liter of 1.0 M glucose with 1.0 liter of distilled water, we double the volume to 2.0 liters and cut the concentration in half to 0.50 M. ... This means that the number of moles of glucose present before the dilution is equal to the number of moles of glucose present after the dilution.

Answer 2

Explanation:

when we add water to a solution, we lower the concentration of the substances dissolved in that solution through a process called dilution. We can take advantage of dilution to make solutions of any desired concentration when we start with a more concentrated solution.
