Q. concentration of solutions that involves liquid solute ans solvent uses.

Ans: The concentration of a substance is the quantity of solute present in a given quantity of solution. Concentrations are usually expressed in terms of molarity, defined as the number of moles of solute in 1 L of solution.

Answer 2

Answer:

The concentration of solutions that involves liquid solute and solvent is molality(m).

Explanation:

Molality:

• Molality (m), or molal concentration, is the amount of a substance dissolved in a certain mass of solvent.
• In simple terms, it is defined as the moles of a solute per  kilograms of a solvent
• If a solution is having 'n' no. of moles of solute and the weight of solvent taken is 'M', then the molality of the solution m is given by:

        m = n/M(Kg)

        OR

         M = (n/M (g) )× 1000

• The SI unit of molality is moles per kilogram (mol/kg). For example, a solution whose molality is given as 2 mol/kg is stated as 6 molal or 2 m.

Therefore, the concentration of solutions that involves liquid solute and solvent is molality(m).
