Gases are not measured by linear measures such as feet or meters - they are measured either by mass (pounds, kilograms), or by volume (liters, cubic feet). In the case of a volume, you must also know the pressure.

How many moles of helium atoms are there in 2.4 Times 10 to the 24 power of helium atoms?
1 mole = 6.0 x 1023 atomsSo, 4 mole = 24 x 1023 atoms or 2.4 x 1024 atoms
Ionization energy of a helium atom is helium gas per mole?
the first inoization energy is 2372.3 kJ mol-1 there are 6.0221415 × 10^23 in a mole from avagadros number, devide the ionization energy for one mole by the number of atoms in a mole and you get the first ionization energy for one atom.
What is the total number of atoms contained in a 1 mole sample of helium?
In one mole of helium, there is 6.02 x 10*23 atoms. In 1 mole of any substance, it contains 6.02 x 10*23 particles of that substance. This number (6.02 x 10*23) is known as Avogadro's number or Avogadro's constant.
Does 1 mole of hydrogen atoms equals 1 mole of helium atoms?
Yes. In either case they will be 6.02*10^23.
How many moles are present in 0.12g of helium?
1 mole He is 4.0 g. Use as a conversion factor to change 0.12 g He to moles.
How many moles are there in 0.12g of helium?
4 g or helium is 1 mole. So, 0.12 g of helium is 0.03 mole
How many liters is one mole of helium?
22.4litres
How many moles in 6.45 x 10 tenth grams of helium?
4 g of Helium will have 1 mole. So, 6.45 x 1010 g of Helium will have 1.61 x 1010 mole.
How many moles in 6.071grams of helium?
4 g = 1 mole. So, 6.071 g = 1.52 mole
How many atoms are in helium at room temperature?
4 g (or 1 mole) of helium will have 6.023 x 1023 atoms
How many helium atoms are in a millimole of helium?
So, in a mole of anything, there are 6.022x10^23 molecules or atoms. There are 1000 millimoles in a mole, so 6.022x10^23/1000 is 6.022x10^20 atoms.
How many moles are present in 205 g of helium?
Quite a few! 205 grams helium (1 mole He/4.003 grams) 51.2 moles of helium
Is helium represented by he?
one mole of He
What is the number of atoms in 1.5 moles of helium if you calculate it?
1 mole of helium has 6.023 x 1023 atoms. So, 1.5 mole of helium will have 9.035 x 1023 atoms.
How many mole of helium are contained in a closed system holding 4.85 liters?
You need to specify temeprature and pressure At 0 0C and 1 atmosphere a mole of helium is approxomately 22.4 litres - 4.85 is about 0.21 mol
How many liters are within 3.5 mol of helium gas at STP?
1 mole = 22.414 liters So, 3.5 mole = 78.45 liters
How many helium atoms are there in a helium blimp containing 431 kg of helium?
1 mole or 4 g or 0.004 kg of Helium has 6 x 1023 atoms. So, 431 kg of Helium have 65 x 1028 atoms
