Define the following terms:a) Mole fractionb) Molalityc) Molarityd) Mass percentage
Answers
a) Mole fraction: - It is defined as the ratio of the number of moles of the component to the total number of moles of all the components in the mixture.
b) Molality: -It can be defined as the number of moles of the solute per kilogram of the solvent
c) Molarity: - it can be defined as the number of moles of the solute dissolved in one Litre of the solution.
d)Mass percentage: - Mass percentage of a component of a solution is defined as the mass of the solute in grams present in 100 g of the solution.
☑Mole Fraction:
the mole fraction or molar fraction is defined as the amount of a constituent, nᵢ divided by the total amount of all constituents in a mixture, nₜₒₜ: The sum of all the mole fractions is equal to 1: The same ...
2.Molality, also called molal concentration, is a measure of the concentration of a solute in a solution in terms of amount of substance in a specified amount of mass of the solvent. This contrasts with the definition of molarity which is based on a specified volume of solution.
