vCalc.Mass Fraction of Vapor Phase

The Mass Fraction of Vapor Phase calculator compute the fractional portion of mass based on the mass of the liquid and mass of the vapor.

INSTRUCTIONS: Choose units and enter the following:

  • (mg) This is the mass of the vapor
  • (mf) This is the mass of the liquid

Mass Fraction (x): The calculator returns the fraction as a real number.

The Math / Science

This equation computes the mass fraction of a substance in vapor phase from the mass in vapor and the mass in liquid.  The formula for the mass fraction of vapor phase is:

    x = mg/(mg + mf)
