How to mass an object that is less dense than air?

Ralphonsicus

How does one go about massing an object less dense than air (like a balloon), because gravity can then not be relied on?

What do mean by "massing"? Note - "mass" is a noun, not a verb.

Buoyancy! This page should help: http://hyperphysics.phy-astr.gsu.edu...pbuoy4.html#c2

Just pretend you are weighing the object underwater and the page should work fine. If you want to do the calculations by hand you can find them on wikipedia's page on Buoyancy as well as on the first site linked.

Having trouble understanding? Drakkith seemed to cope just fine.

Thanks, just what I was looking for.

It's important to always be clear as to what you are asking.

Place the object on a digital scale inside of a vacuum chamber.
