There is a 5.24 ppm of He in air. ppm means that 5.24 parts of helium goes per 1000000 parts of air (million part of air). In % this would be 0.000524% of He.

What has more density air or helium?
The density of helium is less than the density of air. You can infer this without doing any calculations by thinking about the classic example of inhaling the helium from a balloon and talking. Your voice gets squeeky high because helium is less dense than air - that is, your sound waves propagate faster through helium than through air, therefore helium is less dense.
Does helium have more density than air?
Yes, all substances have density. Helium has a density of 0.1664 g/liter at 20°C and one atmosphere of pressure.
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
Why do balloons only float with helium?
they don't float ONLY with helium. They float with any gas that is less dense than air, for instance hydrogen.
Where is the element helium in found in nature?
Helium is found in the sun. It is also found in the Earth's atmosphere.
What has more chemicals helium or air?
Air has many more different substances than helium, which is a single substance. Outside air contains helium.
Why does a helium balloom float in air?
Helium is lighter than air. so balloons filled with helium will float in air
What element is lighter than air?
There are many, but one is Helium
How does helium make a balloon rise when air doesn'?
Helium is lighter than air. So helium balloon rises in air.
Helium hydrogen and air are in this state of matter?
Helium, hydrogen, and air are gases.
What objects contain helium?
Helium is generally used in helium balloons and blimps. Helium is lighter than air and these items will float in air
What happen when a balloon is filled with helium?
Helium is lighter than air and a balloon filled with helium may rise up.
Is air heavy than helium?
Yes. air is heavier than helium.
What is helium gas or air?
helium is a gas. air is a bunch of different gasses.
Why does a helium ballooon float in air?
Helium has a lower density than air.
How does a helium balloon float but not a balloon filled with air?
Helium is a lighter element compared to air, helium also has fewer molecules than air.
Why does a helium balloon float in the air rathen than sink?
because helium is ligter than air
