Question

Write The Relation Between Molality And Mole Fraction

Answer 1

Answer:

The mole fraction of any component of a solution is defined as the ratio of the number of moles of that component present in the solution to the total number of moles of all the components of the solution.

Mole fraction = \frac{Number of moles of solute}{Number of moles of solvent}Molefraction=

Numberofmolesofsolvent

Numberofmolesofsolute

mole fraction = \frac{n_{B}}{n_{A}+ n_{B}}molefraction=

nB= number of moles of solute

nA = Number of moles of solvent

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

Molality = \frac{Moles of solute}{Moles of solvent}Molality=
