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.
No, 1 mole of hydrogen atoms does not equal 1 mole of helium atoms. One mole of any element contains Avogadro's number of atoms (6.022 x 10^23), so 1 mole of hydrogen atoms would have that many hydrogen atoms, while 1 mole of helium atoms would have that many helium atoms.
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.
1 mole = 6.0 x 1023 atomsSo, 4 mole = 24 x 1023 atoms or 2.4 x 1024 atoms
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.
To calculate the number of moles in 0.12g of helium, you need to use the molar mass of helium. The molar mass of helium is approximately 4g/mol. Therefore, 0.12g of helium is equivalent to 0.12g / 4g/mol = 0.03 moles of helium.
4 g or helium is 1 mole. So, 0.12 g of helium is 0.03 mole
No, 1 mole of hydrogen atoms does not equal 1 mole of helium atoms. One mole of any element contains Avogadro's number of atoms (6.022 x 10^23), so 1 mole of hydrogen atoms would have that many hydrogen atoms, while 1 mole of helium atoms would have that many helium atoms.
4 g (or 1 mole) of helium will have 6.023 x 1023 atoms
To find the number of moles in 6.071 grams of helium, divide the given mass by the molar mass of helium. The molar mass of helium is approximately 4 grams per mole. Therefore, 6.071 grams / 4 grams/mol ≈ 1.52 moles of helium.
One mole of any gas at standard temperature and pressure (STP) occupies 22.4 liters. Therefore, one mole of helium would also occupy 22.4 liters at STP.
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.
one mole of He
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
1 mole = 22.414 liters So, 3.5 mole = 78.45 liters
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.
Lead. The molar mass of lead is 207.2 g/mol while helium's is 4.0 g/mol.
1 mole of helium (or 4 g or 0.004 kg) will have 6 x 1023 atoms. So, 544 kg will have 8.16 x 1028 atoms.
