Calculate the density of the hydrogen and air density and mass for the following gases: CO2, H2S

Calculation for CO2.
Density for hydrogen:
D = Mr (CO2) / Mr (H2) = 44/2 = 22.
Density by air:
D = Mr (CO2) / Mr (air) = 44/29 = 1.5.
Carbon dioxide mass:
m = n * Mr = 1 * 44 = 44 g.
Calculation for H2S.
Density for hydrogen:
D = Mr (H2S) / Mr (H2) = 34/2 = 17.
Density by air:
D = Mr (H2S) / Mr (air) = 34/29 = 1.17.
Hydrogen sulfide mass:
m = n * Mr = 1 * 34 = 34 g.
