How to Convert Mass Fraction to Mole Fraction Using CO2?

Click For Summary
SUMMARY

The conversion of mass fraction to mole fraction is achieved by utilizing the molecular weight of the substance in question, specifically carbon dioxide (CO2) in this discussion. To convert, one must first determine the mass fraction of carbon (C) within one mole of CO2, which consists of one mole of carbon and two moles of oxygen. The total mass of CO2 is calculated, and then the moles of carbon are derived from the total moles of elements present in one mole of CO2. This method provides a clear pathway for accurate conversion.

PREREQUISITES
  • Molecular weight calculation
  • Understanding of mass fraction
  • Knowledge of mole fraction

You can try using an example like CO2
Check mass fraction of C with total mass in one mole of CO2 and then check moles of carbon in total moles of the elements in one mole of CO2.
