Mole fraction unit is very useful in relating some physical properties
of solutions, say vapour pressure with the concentration of the
solution and quite useful in describing the calculations involving
gas mixtures Rationalised 2023-24

Calculate the mole fraction of ethylene glycol (C2H6O2) in a solution
containing 20% of C2H6O2 by mass Assume that we have 100 g of solution (one can start with any amount of
solution because the results obtained will be the same) Solution will
contain 20 g of ethylene glycol and 80 g of water
