What is the volume of 10.9 mol of helium at STP?
The volume of 10.9 mol of helium at STP is 50 litres.
How much does 75.0 L of helium weigh?
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.
What would the volume of 28g of helium be at STP?
It would be 7 x 22.4 litre ie 156.8 litre.
Why does HE have a molar volume of 22.4dm3 at stp and ch3cl have a molar volume of 21.9dm3 at stp?
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
10mL of Helium equal to how much gram?
Helium weighs about 1/7 the weight of air. Air weighs about 1.2 g / L. Helium weighs about 0.17 g / L. 10mL of Helium would weigh about 0.0017 grams.
What is the volume of 10.9 mol of helium at STP?
The volume of 10.9 mol of helium at STP is 50 litres.
What is the answer to this conversion 0.0396 moles of helium into liters at STP?
The volume is 0.887 L.
What is the mass of 43.7 L of helium at STP?
The mass of 43,7 L of helium at STP is 7.8 g.

What is the state of for helium?
Helium exists as a gas at STP
What is the state of matter by helium?
Helium is a gas at STP.
At STP 32 grams of O2 would occupy the same volume as?
PV=nRT 32 gram O2 = 1 mole O2 (1atm)(V) = (1 mole)(.0821)(273) V = 22.4 L
10mL of Helium equal to how much gram?
Helium weighs about 1/7 the weight of air. Air weighs about 1.2 g / L. Helium weighs about 0.17 g / L. 10mL of Helium would weigh about 0.0017 grams.
What is the nature of helium?
gas at STP
What would be the volume of 6.00 g of helium 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.
