A helium balloon contains 0.46 g of helium how many moles of helium does it contain?
To find the number of moles of helium in the balloon, you need to divide the mass of helium by its molar mass. The molar mass of helium is approximately 4 g/mol. Therefore, 0.46 g of helium is equal to 0.46 g / 4 g/mol = 0.115 mol of helium in the balloon.
What is the simble for helium?
The symbol of Helium is He. Helium's atomic number is 2.
What are the symbols for hydrogen and helium?
The symbol for hydrogen is H, and the symbol for helium is He.
Is helium easy to find?
kind of you can find it on the stars and some gas planets and a little bit on earth
Is helium paramagnetic?
AnswerThere are two variants of helium -- helium 3 and helium 4. Helium 4 is not magnetic but helium 3 is. Its magnetism is, however, of different nature than e.g. that of iron. The magnetism of helium 3 is used for medical lung imaging.
Where is a common place to find helium?
Helium is found in the atmosphere.
What is the most common place to find helium?
Helium is a gas. It is found in traces in the Earth's atmosphere.
Does helium atom in the Sun have the same physical properties as helium atom on Earth?
No. the size of helium is the same everywhere.
A scientist is studying the Sun's corona What will he find?
he will find lots of gas and helium
How many neutrons would you expect to find in a helium atom?
There are several isotopes of Helium and they have different numbers of neutrons. The simplest and most common is Helium-4 which has two neutrons
How did Pierre janssen find helium?
he found it in the middle of an eclipse. he saw a yellow line across the sky which turned out be helium.
How many moles of Helium are in 6.46 g of Helium?
Helium is 4g/mol, so 6.46g of helium is 6.46/4=1.62 moles He.
Is helium a pure or a compound elements?
Pure i belive. Allthough its a gass so its probably hard to find unmixed.
A helium balloon contains 0.46 g of helium how many moles of helium does it contain?
To find the number of moles of helium in the balloon, you need to divide the mass of helium by its molar mass. The molar mass of helium is approximately 4 g/mol. Therefore, 0.46 g of helium is equal to 0.46 g / 4 g/mol = 0.115 mol of helium in the balloon.
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.
Where can you find helium balloons in new zealand?
Helium grade balloons can be purchased at most large stationary stores, if you desire them to be filled with Helium then a gas supply store would be your best bet.
How many helium atoms are there in a helium blimp containing 590 kg of helium?
To find the number of helium atoms, we need to convert the mass of helium to moles and then use Avogadro's number to convert moles to atoms. The molar mass of helium is 4 g/mol. First, convert 590 kg to grams (590,000 g). Then, divide by the molar mass of helium to find moles, and finally multiply by Avogadro's number (6.022 x 10^23 atoms/mol) to get the number of atoms.
