The mass percent, molality, molarity and mole fraction of Cesium chloride has to be calculated. Concept introduction: The mass percent can be defined as the mass of solute in grams to the total mass of solute in grams is multiply in 100 . It can be given by the equation, Mass %= Mass of solue(in g) Total mass (in g) ×100 Molality of a solution also called as molal concentration can be defined as the mass of solute in grams to the mass of the solvent in kilograms. It can be given by the equation, Molality(mol kg -1 )= Mass of solue(in g) Mass of solvent(in kg) Molarity can be defined as the moles of solute (in grams) to the volume of the solution (in litres). The molarity of a solution can be given by the formula, Molarity(M)= Moles of solute(in g) Volume of solution(in L) Mole fraction of a compound can be defined as the number of moles of a substance to the total number of moles present in them. The mole fraction can be calculated by, Mole fraction of compound= Number of moles(in mol) Total number of moles(in mol)
