Question

(a) Define: a) Mole Fraction b) Molality

c) What is the basic difference between electron gain enthalpy and electronegativity​

Answer 1

Mole Fraction :-the ratio of the number of moles of one component of a solution or other mixture to the total number of moles representing all of the components.

Molality is defined as the “total moles of a solute contained in a kilogram of a solvent.”

Molality :- is also known as molal concentration. It is a measure of solute concentration in a solution. The solution is composed of two components; solute and solvent. There are many different ways to express the concentration of solutions like molarity, molality, normality, formality, volume percentage, weight percentage and part per million. The term needs to calculate the mass of the solvent and moles of solute.
