How many moles are present in 0.12g of helium?
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.
How many helium atoms are in 542 kg 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.
How do you use the word helium in a sentence?
The helium balloon went into the air with no problem, scientist watched with satisfaction as their project had succeeded.By: Nguyen :P
What is Number of orbitals in helium?
Helium has two electrons, and each electron occupies an orbital. Therefore, in a helium atom, there are two orbitals, one for each electron.
Is the helium in a balloon a substance or a mixture?
Helium is an element (and therefore a pure substance) yes
What is a common use for helium?
helium balloons
What can i use instead of helium?
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!!
What is one use of helium at room temperature?
Helium at room temperature is commonly used to inflate balloons due to its low density, making balloons float.
How can you test for helium?
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.
How many kinds of atoms does helium have?
Helium has one kind of atom: helium.
Why you use he in helium neon laser?
helium is used for excitation of neon atoms in helium neon laser..
How many gases is there in helium?
Helium has only one type of gas (which is helium itself)
How helium use?
Inhale
Which balloon would fly higher the one with helium or the one with air?
The balloon with helium.
How many elements does helium have?
ONE, Helium is an element, not a molecule.
What is one important use for helium?
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.
What is the main use of helium?
the use for balloons mostly
