Molar fraction is a measure of the proportion of a substance in a mixture, expressed as the number of moles of the substance divided by the total number of moles in the mixture. Mass fraction, on the other hand, is a measure of the proportion of the mass of a substance in a mixture, expressed as the mass of the substance divided by the total mass of the mixture. To convert from molar fraction to mass fraction, we need to know the molar mass of the substance. The formula for the conversion is:
Mass fraction = (Molar fraction) x (Molar mass) / (Total mass of mixture)
Therefore, to convert from molar fraction to mass fraction, we need to multiply the molar fraction by the molar mass of the substance and divide by the total mass of the mixture. This will give us the mass fraction of the substance in the mixture.
