SpletRelative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity for liquids is … SpletThe first thing we need to do is derive a formula for a gas's density. We can do it from the ideal gas law. Start with the ideal gas law: PV=nRT. Solve the density equation for volume: ρ=mV→V=mρ. Insert volume into the ideal gas law: P×mρ=nRT. Solve for density: ρ=P×mnRT. Simplify by converting moles to molar mass (M): ρ=P×mMm×R×T.
