How much helium is in a balloon that contains 0.54 grams of helium gas?
To calculate the amount of helium in the balloon, we need to convert the mass of helium gas to moles using the molar mass of helium. The molar mass of helium is 4 g/mol. So, 0.54 grams of helium is equal to 0.54/4 = 0.135 moles of helium. Finally, we can use Avogadro's principle to convert moles to the number of helium atoms present in the balloon.
Is helium inside a balloon a compound?
No, helium inside a balloon is not a compound. Helium is a chemical element and is the second lightest element on the periodic table. It exists as individual helium atoms inside the balloon.
What will a helium filled balloon do in space?
In space, a helium-filled balloon will expand further due to the lack of air pressure outside the balloon. Eventually, the balloon will burst because the pressure from the helium inside will exceed the pressure outside.
Why do helium balloons shrink and stop floating?
Helium filled balloons stop floating because the helium leaks out. The balloon latex is porous and the helium is a very small atom and leaks out causing the balloon to lower and eventually stop floating.
Why does helium balloons shrink?
Helium balloons can shrink over time due to the small helium atoms diffusing through the walls of the balloon, which are not completely impermeable. This leads to a gradual loss of helium from the balloon, causing it to deflate and shrink.

How many atoms are in a balloon?
The number of atoms in a balloon would depend on the size of the balloon and the gas inside it. However, a typical sized balloon filled with helium might contain around 1x10^22 atoms.

Is helium in a balloon a pure substance not a mixture?
In theory it is a pure element. However, due the the cost of obtaining really pure helium, it is likely to contain trace amounts of other gases.
Which has the least number of atoms 5g of hydrogen or 10g of helium?
10g of helium has fewer atoms. This is because the atomic mass of helium is much higher than that of hydrogen, so the same mass of helium contains fewer atoms than the same mass of hydrogen.

Why after 24 hours helium balloon won't fly what is happening with the helium?
Helium atoms are very small and able to diffuse through the balloon material over time, leading to a loss of buoyancy. As a result, the balloon becomes deflated and unable to lift the weight of the rubber and any attachments.
The gas used to fill party balloons contains only helium atoms What does This make helium?
Helium molecules have a lower molecular weight than air. This is why balloons filled with Helium will float in the air. Apex:element
Why does a CO2 filled balloon deflate quicker than a helium filled balloon given that helium atoms are smaller and monatomic?
Well...it's because they're not the same balloons. There is a product out there called Super Hi-Float. You coat the inside of a balloon destined to be filled with helium with it, and it helps seal the pores of the latex hence holding the helium in longer. You probably wouldn't do this with a balloon you're going to fill with CO2.
