Density formula using ideal gas laws
WebDec 9, 2024 · The gases in the atmosphere have a simple equation of state known as the Ideal Gas Law. For dry air (namely, air with the usual mix of gases, except no water vapor), the ideal gas law is: (1.18) P = ρ ⋅ ℜ d ⋅ T where ℜ d = 0.287053 kPa·K –1 ·m 3 ·kg –1 = 287.053 J·K –1 ·kg –1 . ℜ d is called the gas constant for dry air. WebFeb 10, 2015 · Example \(\PageIndex{2}\): Empirical/Molecular Formula Problems Using the Ideal Gas Law and Density of a Gas.
