The volume of 10.9 mol of helium at STP is 50 litres.
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.
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
10 mL of helium at standard conditions (STP) would weigh approximately 0.0125 grams.
The volume of 10.9 mol of helium at STP is 50 litres.
The volume is 0.887 L.
The molar volume of gas at STP is 22.4 L/mol. Helium has a molar mass of 4.0 g/mol. Using the ideal gas law, we can calculate that the mass of 43.7 L of helium at STP is approximately 61.6 g.

Helium is a gas at STP.
Helium exists as a gas at STP
10 mL of helium at standard conditions (STP) would weigh approximately 0.0125 grams.
At STP (standard temperature and pressure), 32 grams of O2 would occupy the same volume as 22.4 liters, which is the molar volume of any ideal gas at STP.

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.
