Density of an Ideal Mixture from Mass Fractions and Component Densities Calculator

1 / ρ_mix = Σ wᵢ / ρᵢ — ideal-mixing rule.

Compute the bulk density of an ideal liquid mixture from up to three components, each given as a mass fraction (decimal, summing to 1) and pure-component density. The reciprocal of the mixture density equals the mass-weighted reciprocal of the component densities: 1 / ρ_mix = Σ wᵢ / ρᵢ.
