Answer : All the given options are applicable for a solution’s concentration.
Explanation :
(1) The physical properties of a solution are not affected by the concentration of the components.
This statement is apply to a solution's concentration. Physical properties can be measured without changing the composition of substance. For example : The boiling point of 2 gram substance and 10 grams of substance will always remain same.
(2) Boiling points and freezing points of solutions change as the concentration of the solute changes.
This statement is apply to a solution's concentration. As we know that the boiling and freezing point of solution depends on the number of moles of solute or concentration of solute. So, as the concentration of solute changes the boiling and freezing point of solution.
(3) Moles of solute = (Liters of solution) x (Molarity of solution)
This statement is apply to a solution's concentration. As we know that the molarity is defined as the number of moles of solute present in one liter of volume of solution.
(4) (Initial Concentration)(Initial Volume) = (Final Concentration) (Final Volume)
This statement is apply to a solution's concentration as per dilution law.
(5) Concentration affects if an acid is weak or strong.
This statement is apply to a solution's concentration. As the concentration of an acid and base is the amount of moles of solute per unit volume. That means if a solution has higher molarity, then the concentration is also higher and vice-versa.
Hence, all the given options are applicable for a solution’s concentration.
