Air has mass, therefore, air has weight.
Mass and weight are dependent solely on the amount of the substance being measured. The more of the substance, the more mass and the higher the weight.
You did not specify an amount of air, just "the" air.
Did you mean all of the air on Earth?
Dry air has a density of 1.2 kg/m^3 at 20 degrees C and 1 atm of pressure.
In order to find the overall mass of the air, multiply the density by the volume of air in question.
To find the weight of the air, multiply the mass by the gravitational acceleration experienced by air (9.81 m/s^2 on the surface of Earth).

Air is surrounding the whole earth.
Weight is the force of an object toward the center of earth.
Hence you cannot ask what the weight of air is.
The earth is having large volume of water on its surface.
Is it correct to ask, ‘what the weight of water of earth is?’
One can instead ask what the mass of air surrounding the earth is.
Over an area we can calculate the weight of air.
Since pressure = force/ area, Measuring the area and knowing the air pressure over an area we can calculate the weight of air column over that area.

Air exerts a pressure of 14.7 psi approximately at see level. The weight of air depends on the density which depends on pressure, humidity and temperature. For argument sake, say sir weighs nothing.

The weight depends on the mixture of gases that's in the air. Calculate the weight under earth's gravitational pull by the mass of the modules. So given a certain volume, u have a certain amount of mass.
An object's weight is equal to its mass mulitplied b the net acceleration. Please consult wikipedia.org for a full definition of weight.

My recollection is that air weights about 0.075 pounds per cubic foot at sea level. At higher elevations air becomes less and less dense because there is less weight of air above to compress it. An entire column of air from sea level to the edge of space weighs about 14.7 pounds per square inch.

Air indeed has weight -- what do you think air pressure is?

I would think it is nothing

It depends on what you ate.
LOL.
