If I fill a balloon with helium it will float. Why does it float? Estimate the mass of helium in the balloon.

It only makes objects float if they are less dense than their surroundings, like a boat on water, or a helium balloon in air. Buoyancy works due to displacement. ... In the case of a balloon, the helium inside the balloon weighs less than the same volume of air the balloon displaces

Explanation:

In the case of a balloon, the helium inside the balloon weighs less than the same volume of air the balloon displaces. ... So a helium balloon has two opposing forces acting on it: gravity pulling it down, and buoyancy pushing it up. Buoyancy wins, so you can't really weigh a balloon, even though it does have weight.

Knowing the volume of air displaced by the helium balloon, we can calculate the maximum mass the balloon can lift. ... Helium, which has a mass of 4.00 g/mol, has a density of 0.164 g/l. Thus, a one-liter balloon of helium can lift a mass of (1.18-0.164) = 1.02 g.

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
