We can answer that, but the answer isn't simple. Try to stay with us here:
First of all, it depends on the temperature, pressure, and humidity of the air.
For dry air at a temperature of zero Celsius (32 Fahrenheit) and pressure of
760 mm Hg, the density is
1.2929 gram per liter = 1.2929 kilogram per m3 .
The weight of 1.2929 kilogram is 12.67 newtons (2.85 pounds). (rounded)
BUT . . . . .
Don't forget that anything surrounded by a fluid is buoyed up by a force equal to
the weight of the displaced volume of fluid. So our cubic meter of air is buoyed up
by a force equal to the weight of a cubic meter of air, and winds up weighing zero !
Surrounded by vacuum, it weighs about 2.85 pounds. But surrounded by more air,
it weighs exactly nothing.
Which is why every cubic meter of air in the room doesn't fall down on the floor.

how much do you Weigh? How much does the parcel Weigh?
54.88 kg
you should weigh 85 pounds
Which air plane? A 747 weighs several hundred tonnes more than a Cessna, even with the engines removed
it would depend on the mass of the object. like you could have a quart of air or a quart of maple syrup. which ones going to be heavier
