0 air is nothing
it's because of the ratio of the weight of the air in the balloon to the air outside the balloon
Sound in air is simply a compression of air at the frequency of the sound. The sound itself does not weigh anything, but the medium it is travelling in will have its own weight per unit volume.
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.

It is difficult to weigh air, since air has a buoyancy that is exactly equal to its own weight (being surrounded by more air) - sort of like trying to weigh water while you are underwater. However, if you had a vacuum chamber in which you could work (wearing a spacesuit so you could breathe) then you could weigh air, inside a container (you would also have to weight the container separately, of course). A triple beam balance is sensitive enough for this job, if you use a large container.Alternatively, you could weigh a light weight can, and then evacuate it and weigh it again. It will weigh less by the quantity of air excluded. But it is important that the can remains the same shape after evacuation, but your vacuum need not be particularly good for a reasonable measurement.The mass of dry air is approx 0.0012 grams per cm3. Or about 1.2kg per m3. (check my math.)
The weight of a hot-air balloon can vary depending on its size and design. On average, a small hot-air balloon can weigh around 250-400 pounds (113-181 kilograms), while larger ones can weigh over 1,000 pounds (453 kilograms) or more.
nothing, air doesn't weigh anything
Take a large container, pump out all the air from inside it. Weigh it. Put air inside and then weigh it again. The difference would be the weight of the air inside. Air molecules have mass (air is "stuff") and things with mass have weight when in a gravitational field, such as on Earth. If air didn't have any weight, we wouldn't even have an atmosphere.
Wait a couple of hundred years and put anti-gravity in it. Put air in it and take it on a ride on the vomit comet aircraft to have the barrel experence weightlessness. Maybe you could just take the top off and let it fill with the sorrounding air and it will weigh less while the top is off. BEST ANSWER: A HOLE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!11
Mac book air weight is 2.3pound (1.06kg)
Air conditioners vary in weight. Some air conditioners can weigh more than a ton, while others only 50 to 60 pounds.
One pound. Or sixteen ounces. Or .45 kilograms. Whichever you prefer.
Well in theory there won't be a difference in weight when at atmospheric pressure because air doesn't weigh anything on a scale open to the atmosphere but when the pump is in a vacuum and it contains air it will weigh more.

There can be no conversion.A kilogram is a measure of mass. A cubic metre is a measure of volume. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid.Consider a cubic metre of air. How many kilograms? Next consider the same volume of lead. How many kilograms?
noAnswer:Of course. However what you really want to do is determine the mass of the balloon, not the weight. In the cases below the term weight is used to express the concept of "the reading on a scale relating to the mass at the surface of the earth":If you are talking about empty balloons you just put them on a scale and weigh them directlyIf you are talking about air filled balloons (they fall to the ground when you drop them) you weigh them on the scale filled, then calculate their volume. If you know the atmospheric pressure and relative humidity you add the weight of air they displace and add it to the scale weight.If you fill them with a lighter than air gas you weigh the lift (invert the scale and see how hard they push up) then by the same method as previously calculate the weight of the air they displace and subtract the "weight" of the liftIf you are working with hot air balloons it's (the weight of the air they displace) - (the weight they can lift)
