Helium is not very dense especially because it is a gas, hence when you inhale helium it makes your voice high pitched because the low density the sound waves are travelling through lets the sound waves go faster, it is like fast forwarding a video or a sound the pitch get higher and higher the faster you go.
The volume of 10.9 mol of helium at STP is 50 litres.
yes i does

4 g of helium occupy 22.414 liters. So, 84.6 g of helium occupy 474.056 liters.
31 pm This is not correct the best answer for helium would be 0.0 or n/a Helium also has no covalent radius. The atomic volume of helium is 31.8

Helium accounts for around 8% of the volume of all matter (baryonic particles) in the universe.
depends on the size of its container and volume of helium filling it
The surface of the Sun consists of hydrogen (about 74% of its mass, or 92% of its volume), helium (about 24% of mass, 7% of volume), and trace quantities of other elements, including iron, nickel, oxygen, silicon, sulfur, magnesium, carbon, neon, calcium, and chromium.
The density will be 50 % from the initial value.

yes it is because it has a lesser volume
4 g of helium occupy 22.414 liters. So, 84.6 g of helium occupy 474.056 liters.
The volume of the Earth is 50 times greater than the volume of the Moon.
"Neither a definite shape nor a definite volume" means it is a gas. Several elements are gases at that temperature, including all noble gases (helium, xenon, neon, and others); and a few others, such as hydrogen, oxygen, fluor, nitrogen.
If you mean the air we breathe, the meter stick will lean towards the balloon with the greater volume of air in it. However, if you fill the balloons with helium, the meter stick will lean toward the balloon with less helium, since helium makes balloons float.
