1. Find the number of moles of hydrogen gas:
* The molar mass of hydrogen gas (H₂) is 2 g/mol.
* Number of moles = (mass of hydrogen gas) / (molar mass of hydrogen gas)
* Number of moles = 1 g / 2 g/mol = 0.5 moles
2. Find the number of hydrogen molecules:
* Avogadro's number is 6.022 x 10²³ molecules/mol.
* Number of molecules = (number of moles) * (Avogadro's number)
* Number of molecules = 0.5 mol * 6.022 x 10²³ molecules/mol = 3.011 x 10²³ molecules
3. Find the number of electrons:
* Each hydrogen molecule (H₂) contains 2 hydrogen atoms.
* Each hydrogen atom has 1 electron.
* Number of electrons = (number of molecules) * (number of atoms per molecule) * (number of electrons per atom)
* Number of electrons = 3.011 x 10²³ molecules * 2 atoms/molecule * 1 electron/atom
* Number of electrons = 6.022 x 10²³ electrons
Therefore, there are approximately 6.022 x 10²³ electrons in 1 gram of hydrogen gas.
