what is the density of air in g/ml
The density of air ρ (Greek: rho) (air density) is the mass per unit volume of Earth's atmosphere. Air density, like air pressure, decreases with increasing altitude. It also changes with variation in atmospheric pressure, temperature and humidity. At 101.325 kPa (abs) and 15 ° C, air has a density of approximately 1.225 kg / m3 (0.001225 g / cm3, 0.0023769 slug / (cu ft), 0.0765 lb / (cu ft)) according to ISA (International Standard Atmosphere).
