Question

Mole concept Molarity, Molality and calculation of empirical formula.​

Answer 1

Explanation:

Mole fraction = mole fraction is the ratio of number of moles of one component to the total number of moles of solute and solvent present in the solution.

mole fraction of a component = number of moles of the component/total number of modes of all components.

molality

molality of a solution is defined as the number of mole of the solute dissolved per 1000 gram or 1 kg of the solvent.

molality= mass of solute/mass of solvent in kg.

molarity

molarity of a solution is the define is the number of mole of a solute dissolved per litre of the solution.

molarity= mass of solute/volume of solution in litre.
