Which of the following apply to a solution’s concentration.
all that
the physical properties of a solution are not affected by the concentration of the components.
boiling points and freezing points of solutions change as the concentration of the solute changes.
moles of solute = (liters of solution) x (molarity of solution)
(initial concentration)(initial volume) = (final concentration) (final volume)
concentration affects if an acid is weak or strong.

All of them apply according to the exam your are on because they all need concentration to work up the certain chemical

Explanation

The physical properties of a solution are not affected by the concentration of the components.

Boiling points and freezing points of solutions change as the concentration of the solute changes.

Moles of solute = (Liters of solution) x (Molarity of solution)

(Initial Concentration)(Initial Volume) = (Final Concentration) (Final Volume)

Concentration affects if an acid is weak or strong.

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
