Question

air has weight right or wrong​

Answer 1

Yes AIR HAS WEIGHT

Anything with mass has weight, and we know air has mass because (for example) we can feel it when the wind blows. The total weight of the atmosphere exerts a pressure of about 14.7 pounds per square inch at sea level. You don't notice this weight, however, because you are used to it

Answer 2

Explanation:

If compressed air weighs more than noncompressed air, then air must have weight. Compressing a weightless substance would not make it heavier. So the misconception was in the explanation, not the experiment. You are not comparing a balloon of air with an empty one to show that air has weight.
