Expert Answer:

Mole fraction of a component =Number of moles of the component / Total number of moles of all the components

Strength of a solution is defined as the amount of solute in grams present in one litre of the solution.

mass / mass % =(Mass of the component in the solution *100) / Total mass of the solution

Mass by volume percentage (w/v): Mass of the solute dissolved in 100 mL of solution.

volume / volume % (v/v) =( Volume of the component * 100 ) / Total volume of solution

Molarity =    Molality (m) is the number of moles of solute present in 1kg of solvent. 

 Molarity (M) is the number of moles of solute present in 1L of solution.

 Normality is the number of gram equivalent of solute dissolved per litre of solution.

Vapur density = ½ × molar mass

Specific gravity = Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water.
