  • Concentration lectures - molar fraction - ChemBuddy

    Concentration lectures » molar fraction. Molar fraction is defined as ratio of number of moles of substance to total number of moles of all substances. For example 10 molal water solution of ethanol contains 10 moles of ethanol for every 1000 g of water. 1000 g of water is 55.51 mole - and molar fraction of ethanol is 10/(55.51+10)=0.1527.
