Identify the weight of balloon with air. And identify the mass of the balloon. Now subtract the second from the first. You get the mass of the air present in it.
The three properties of air are weight, mass, and density.
The weight of object will be half of that on the surface of earth.It can be proved with law of universal gravitation

Anything with mass has weight; air has mass, therefore it has weight.
Air does not cover space. Air is the atmosphere of the Earth and as you ho higher the air gets thinner and thinner.
The weight of the air on the earth is called... Air Pressure
