7.6.4.2.18. From_Mass_Fraction

Syntax: Density [{of} SpeciesName] = From_Mass_Fraction
Scope: Aria Material
Summary: Species density computed from mass fraction
Description: $\rho_i = \rho * Y_i$

where $\rho$ is the overall density, $\rho_i$ the species density, and $Y_i$ the mass fraction of the species. This model should only be used for the density of a species.
