Explanation:

Mole Fraction - it is defined as the ratio of number of moles of one component to the total number of moles of solute & solvent present in the solution.

) Molality- it is the number of moles of the solute dissolved per 1000g of the solvent.

Molarity- it is the number of moles of the solute dissolved per litre of the solution.

Mass Percentage- the mass percentage of a component in a given solution is the mass of the component per 100g of the solution.

Answer 2

Answer:

• Mass percent: Mass per cent is a way of expressing a concentration or describing the component in a particular mixture
• Molarity: Molar concentration is a measure of the concentration of a chemical species, in particular of a solute in a solution, in terms of amount of substance per unit volume of solution.
• Molality: Molality is a measure of number of moles of solute present in 1 kg of solvent. This contrasts with the definition of molarity which is based on a specified volume of solution. A commonly used unit for molality in chemistry is mol/kg. A solution of concentration 1 mol/kg is also sometimes denoted as 1 molal.
• Mole Fraction: In chemistry, the mole fraction or molar fraction (xi) is defined as unit of the amount of a constituent (expressed in moles), ni divided by the total amount of all constituents in a mixture
