| 1. Determine the relative density of nitrogen:
DN2 (O2) = M (O2): M (N2);
M (O2) = 16 * 2 = 32 g / mol;
M (N2) = 14 * 2 = 28 g / mol;
DN2 (O2) = 32: 28 = 1.1429;
2.find the relative density by air:
Dair (O2) = M (O2): M (air);
M (air) = 29 g / mol;
Dair (O2) = 32: 29 = 1.1034.
Answer: DN2 (O2) = 1.1429; Dair (O2) = 1.1034.
