What is the weight of of air called?

Answer 1

The weight of air is called air pressure. There is no way around air pressure and it must be calculated into anything having to do with physics.

Answer 3

Depends on the mass of the collective amount of air molecules exerting force (weight) on whatever you're using to weight it. A little bit of air weighs very little and some molecules such as helium weighs less (technically it's less dense) air normally.

Answer 4

Air does not have a true molecular weight because it is not a true compound; it is a mixture instead and does not always have the same composition.

Answer 5

It depends on the model and type. If you are talking about a breathing air compressor they weigh any where from 75 pounds to a few tons.
