If James is holding that much helium, he would be talking funny

A helium-filled balloon contains 0.26 mol He at 101 kPa and a temperature of 21 and degC. What is the volume of the gas in the balloon?
6.3 L
Is a helium balloon a solid?
A helium "balloon" is composed of two parts: the SOLID rubber balloon skin, and the GASeous helium. So the balloon part itself is a solid.
Is a helium a metal or nonmetal?
Helium is a nonmetal. Think about the helium balloon!
Which gas is pumped into a balloon?
Helium gas is pumped into a balloon.
What are the periodic elements in a balloon?
Helium.
Why does a helium balloon lower after a while?
That would happen after it loses a certain amount of helium.
Why does the balloon rise?
because it contains helium that is lighter than air
How high do helium balloons fly before they pop?
Depends on the type of rubber and amount of helium in balloon
What will happen if you leave a balloon over night?
A small amount of air or helium within the balloon will escape through the balloon material.
A helium balloon contains 0.46 g of helium how many moles of helium does it contain?
0.46 divided by the formula weight of helium (4) 0.46/4=0.115 or 0.12 moles of Helium
A helium-filled balloon contains 0.26 mol He at 101 kPa and a temperature of 21 and degC. What is the volume of the gas in the balloon?
6.3 L
When a helium balloon rises in the air it expands. If the volume of the balloon doubles what happens to the density of the helium inside it?
The density will be 50 % from the initial value.
Does helium contract in cold weather and cause a helium balloon to sink and if warmed will it rise again?
Helium will contract in cold weather, but that may not cause a balloon filled with it to sink since the air will also contract - and by about the same amount - so the relative densities of the helium and the surrounding are would remain about the same and the buoyancy of a helium filled balloon would remain
Why does a helium balloon pop as it goes higher in the sky?
a helium balloon pops as it goes higher because the different combination of pressure. you could take a balloon in an airplane because the cabin is pressurized. as it gets higher the amount of pressure changes so it pops the balloon.
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.
Which gas do hot air balloons contain?
A hot air balloon contains helium. M. Saffi.Ullah
