Air contains a mixture of dry air and water vapor. The amount of water vapor is a function of the relative humidity, it is also related to the dew point temperature of the air. To calculate the density of air, you need to calculate the partial pressure of the dry air and the partial pressure of the water vapor. as it turns out, you can calculate these using measurements of air temperature, air pressure, and dew point temperature as inputs.
Air Density Equation
ρ = (pd / (Rd * T)) + (pv / (Rv * T))
where:
pd - pressure of dry air in hPa
pv - water vapor pressure in hPa
T - air temperature in Kelvins
Rd - specific gas constant for dry air equal to 287.058 J/(kg·K)
Rv - specific gas constant for water vapor equal to 461.495 J/(kg·K)
*This is a universal app that work for both iPhone and iPad.
