If these atoms are loose unities, not bonded in a molecule, it would be about 22 dm3 at 0oC and standard pressure (STP). If the atoms would have formed gas molecules, e.g. CO2 or SF6, the answer would be different, because 6.02 x 1023 molecules always take in a volume of about 22 dm3 at STP. But with CO2 you would have then 18 x 1023 atoms because there are 3 atoms in one molecule.
helium molecule is mono atomic. 6.023 x 1023 atoms of helium occupy 22.414 liters at STP.
So 4.02 x 1022 atoms will occupy 1.5 liters at STP
One mole of any gas at STP occupies about 22.4 litres. 6g of helium is 1.5 moles so it would occupy 1.5 x 22.4 = 33.6 litres.
6.00 g of helium gas at STP equals 33,6 litres.
22.4L
The volume of 10.9 mol of helium at STP is 50 litres.
It would be 7 x 22.4 litre ie 156.8 litre.
Because at STP, Chloroform is liquid and Helium is in gaseous state. When something is in a gaseous state, it occupies a larger space than the liquid. I thought however, that chloroform would occupy less than that
4 g of helium occupy 22.414 liters. So, 84.6 g of helium occupy 474.056 liters.

The weight of 75.0 L of helium depends on the temperature and pressure at which it is measured. At standard temperature and pressure (STP), which is 0°C and 1 atmosphere, the molar mass of helium is 4.0 grams per mole. Using the ideal gas law, we can calculate the weight by multiplying the molar mass of helium by the number of moles, which is the volume divided by 22.4 L (molar volume at STP). However, if the temperature and pressure are not at STP, additional information is needed to determine the weight.
