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:

- (
**m**) This is the mass of the vapor_{g} - (
**m**) This is the mass of the liquid_{f}

**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 = m_{g}/(m_{g} + m_{f})

where

- x is the mass fraction of the vapor phase
- m
_{g}is the mass of vapor - m
_{f}is the mass of liquid
