How many atoms of hydrogen are in 1 mole of hydrogen gas?
6.022 × 1023 hydrogen atoms For one gram atomic weight of hydrogen with atomic weight of one gram, one mole of hydrogen contains 6.022 × 1023 hydrogen atoms.
How do you find one mole of H2?
Thus we must multiply 6.022 * 1023 by 2 to calculate the number of individual atoms present in 1 mole of H2. We find our answer to be 1.2044 * 1024.
How do you find moles of H2?
Use the mass of the hydrogen gas to calculate the gas moles directly; divide the hydrogen weight by its molar mass of 2 g/mole. For example, 250 grams (g) of the hydrogen gas corresponds to 250 g / 2 g/mole = 125 moles.
