Detailed explanation-1: -The quantity of solute present in a given amount of solution represents its concentration. It is actually the abundance of a constituent divided by the total volume of a mixture or solution.

Detailed explanation-2: -The concentration of a solution is a measure of the amount of solute that has been dissolved in a given amount of solvent or solution.

Detailed explanation-3: -The correct option is A concentration. The quantity of solute present in a given amount of solution represents its concentration. Concentration can be expressed in a number of ways. For example, the number of molecules or ions in a given volume of a substance, is expressed as moles of solute per litre of solution.

Detailed explanation-4: -The most common way to express solution concentration is molarity (M), which is defined as the amount of solute in moles divided by the volume of solution in liters: M = moles of solute/liters of solution. A solution that is 1.00 molar (written 1.00 M) contains 1.00 mole of solute for every liter of solution.

Detailed explanation-5: -If the solute concentration is higher in the external solution than the cell kept in it, then the solution is called as hypertonic.
