Helium is used for inflating balloons and dirigible airships.
To calculate the number of moles in 0.12g of helium, you need to use the molar mass of helium. The molar mass of helium is approximately 4g/mol. Therefore, 0.12g of helium is equivalent to 0.12g / 4g/mol = 0.03 moles of helium.
To find the number of helium atoms in 542 kg of helium, you need to first calculate the number of moles of helium in 542 kg using the molar mass of helium, which is 4 grams/mol. Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles of helium to atoms.
The helium balloon went into the air with no problem, scientist watched with satisfaction as their project had succeeded.By: Nguyen :P
Helium has two electrons, and each electron occupies an orbital. Therefore, in a helium atom, there are two orbitals, one for each electron.
Helium is an element (and therefore a pure substance) yes

You can use air but it won't float so I would recommend helium. If you suck in helium, it will make your voice sound weird.... Try it!!
Helium at room temperature is commonly used to inflate balloons due to its low density, making balloons float.
One common way to test for helium is to use a helium leak detector, which can detect very small amounts of helium gas. Helium can also be identified using a mass spectrometer, since it has a unique mass-to-charge ratio. Additionally, helium can be detected by its characteristic orange glow when placed in an electric field.
Helium has one kind of atom: helium.
helium is used for excitation of neon atoms in helium neon laser..
Helium has only one type of gas (which is helium itself)

ONE, Helium is an element, not a molecule.
Helium is an important natural resource, and is used in a variety of settings. One of these is its use in cooling the powerful magnets used for NMR and MRI, where liquid helium is required in order to achieve their operating temperatures. Another key use is as a carrier gas for Gas Chromatography and GC/MS in analytical and similar laboratories.
