Find the relative density of NO2 oxide by hydrogen and air
| August 27, 2021 | education
The relative density of one gas in another is the ratio of their molar masses, since, as a consequence of Avogadro’s law, equal volumes of gases contain the same number of molecules.
M (NO2) = 46
DH2 (NO2) = 46/2 = 23;
Dair (NO2) = 46/29 = 1.586.
