Helium is much less dense than air, which allows balloons to float. It is also chemically inert, which means hazards associated with it are minimal. Hydrogen gas is lighter and easier to obtain, which would make it seem ideal, but it is also highly flammable, which makes it dangerous.
because it contains helium that is lighter than air
In a balloon filled with helium gas, the helium atoms are evenly distributed throughout the available space. They move freely and randomly due to their kinetic energy, colliding with each other and the balloon's inner walls. This distribution results in a uniform pressure inside the balloon, as the helium atoms exert force equally in all directions. Over time, if the balloon is not tightly sealed, some helium atoms may escape, leading to a decrease in pressure and volume.
A balloon typically contains the element helium, which is a noble gas. It can also contain traces of other elements such as oxygen or nitrogen from the surrounding air or manufacturing process.
0.54 grams 1 mol = mass / Mr = mass / 4 (Helium's atomic weight is 4, it is a monoatomic gas) 1 mol = 0.54 / 4 = 0.00135 # of molecules of helium in the balloon = 0.00135 * 6.02 * 10^23
To find the number of moles of helium in the balloon, you need to divide the mass of helium by its molar mass. The molar mass of helium is approximately 4 g/mol. Therefore, 0.46 g of helium is equal to 0.46 g / 4 g/mol = 0.115 mol of helium in the balloon.

Helium is an inert gas and will not explode. If however your balloon contains Hydrogen gas (which is not inert) instead of Helium gas, and it comes into contact with a flame, it will blow up in your face. (You should google the Hindenberg some time)
depends how big the helium balloon is and how many
A balloon is primarily filled with air, which consists of a mixture of gases, predominantly nitrogen and oxygen molecules. These gas molecules are made up of atoms, specifically nitrogen (N2) and oxygen (O2) particles. When inflated, the balloon contains these gas particles that move freely, creating pressure against the balloon's inner walls. Additionally, if the balloon is filled with helium, it contains helium atoms (He) instead of air molecules.
It was made out of the light gas gas Helium.
The object that already has helium is most likely a helium-filled balloon. Helium is used to inflate balloons as it is lighter than air, causing the balloon to float.
