1 Samples of four gases are released in a room at the same time.
The gases are carbon dioxide, CO₂, hydrogen chloride, HCl, hydrogen sulfide, H₂S, and nitroge
dioxide, NO₂.
Which gas diffuses fastest?

Answer:

H2S

Explanation:

The gas with the smallest molar mass diffuses the fastest (assuming that the holes are the same size and that gasses act ideally).
Find the molar mass of each of the gasses, and then compare.
CO2 = 12 + 16 + 16 = 32 + 12 = 44
HCl = 35.45 + 1 = 36.45
H2S = 1 + 1 + 32 = 34
NO2 = 14 + 16 + 16 =  32 + 14 = 46
Therefor, H2S diffuses the fastest, then HCl, then CO2, and finally NO2
