Name inert gases that are heavier than nitrogen.

It is impossible to weigh nitrogen or air, but its density can be found. The density or mass of air per unit volume of the Earth’s atmosphere is 1.225 kg / m³. This is the density at sea level at 15 ° C.

Some gases are lighter than air:

Ammonia – 0.717 kg / m³.

Helium – 0.1664 kg / m³.

Hydrogen – 0.0899 kg / m³.

Methane – 0.668 kg / m³.

Neon – 0.8999 kg / m³.

Natural gas – 0.7 – 0.9 kg / m³.

Carbon monoxide – 1.165 kg / m³.

Nitrogen – 1.165 kg / m³.

All other gases are heavier than air. For example, argon, carbon dioxide, chlorine, ozone, krypton, oxygen, xenon.
