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.

apologies to the bell ringer but air is more dense than Helium.

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.
Will nitrous oxide float in a balloon?
No, nitrous oxide has a density of around 1.977 grams/liter, "air" at sea level has a density of 1.2 grams/liter, meaning that nitrous oxide is more dense than air. Helium on the other hand has a density of 0.1785 grams/liter, making it less dense than air... Also making helium a popular choice for filling balloons. Hydrogen is another common balloon filling gas. Although it is highly flammable. (Hindenburg)
What is density in air pressure?
The density of water is 1.0 (at 20C), the density of helium is 0.000178 (at 0 C) so ignoring temperature helium would have to be compressed more than 5600 fold . This also ignores state changes (like water to ice) or helium gas to liquid helium).
Does warm air have more density tan cold air?
Not really. Warm air usually has a higher volume than cold air, so its density is usually smaller than that of cold air.
How many helium in the air?
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.
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.
How dense is helium compared with air?
Which is more dense: water or helium? - Water is more dense, because water does not float like helium does. It is below air. That's why we have oceans and lakes and rivers.
Is Density of helium balloon is greater or less than air?
The density of helium is less than that of air. Due to this reason, balloons filled with helium will float in air.
Why does a helium ballooon float in air?
Helium has a lower density than air.
What makes helium great to use in balloons and blimps?
Helium's density is less than the density of air, so it floats in air.
Why does a helium balloon rise in air while ordinary balloon filled with air does not?
A helium balloon rises into the air because the density of the helium is lesser than the density of the air, therefore, the balloon rises, trying to reach above the air. Helium is lighter than air, or to be more precise, less dense. Helium gas weighs less than our atmospheric air so it floats. Same goes for hydrogen and a few other pure gases
Is a canster of air lighter than a canster of helium?
No, helium has the second lowest density out of all the elements and with Hydrogen having the smallest density but it not being in the air it means the canister of air is heavier.
Why does helium rise and regular air sink?
A balloon filled with helium floats and a balloon filled with regular air falls to the ground because helium has less density than air so the air causes the balloon to sink because there are more molecules in it. The helium has less molecules in it so the balloon rises.
Is helium less dense than air?
The molecular mass of helium is 4. The molecular mass of nitrogen, the most common component of air, is 28. Since all gases take up about the same amount of space per mole at a given temperature and pressure, helium is about 7 times less dense than nitrogen, and oxygen, the second most common constituent of dry air, is even more dense than nitrogen.
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.
Why does a helium filled balloon rise in relation to its density?
I'm not sure I understand the question but here goes: Helium is lighter [less dense] than air, so a helium filled balloon rises because it floats up on the more dense air.
What is more dense helium gas or air?
air is more dense than helium
