Molar fraction of the components of a mixture can be calculated as follows;molar fraction of KCl = number of moles of KCl / (mol KCl + H₂O to moles)mass of KCl dissolved - 26.0 gMolar mass of KCl - 74.5 g/molNumber of moles of KCl - 26.0 g/74.5 g/mol = 0.35 molMass of water - 225 g Molar mass of water - 18 g/molNumber of water mol - 225 g /18 g/mol = 12.5 moltotal the number of moles in the mixture - 0.35 + 12.5 = 12.85 molar fraction of KCl - molar fraction of KCl - 0..027
