Answer» Solution :Mole FRACTION : The mole fraction of a component in a mixture 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. i.e., Mole fraction of a complex `= ("Number of moles of the component")/("Total number of moles of all components")` Mole fraction is DENOTED by .x.. If in a binary solution, the number of moles of the SOLUTE and the solvent are `n_(A)` and `n_(B)` respectively, then the mole fraction of the solute in the solution is given by, `chi_(A)=(n_(A))/(n_(A)+n_(B))`, Similarly, the mole fraction of the solvent in the solution is given as : `chi_(B)=(n_(B))/(n_(A)+n_(B))`. |
