How Many Atoms In Hydrogen
Question What is the number of atoms of hydrogen nowadays in one dozen molecules of hydrogen gas? Convert the given number of hydrogen in terms of moles.
Open in App Solution A molecule of hydrogen is formed when two atoms of hydrogen combine with each other. Hence, one molecule of hydrogen contains two atoms of hydrogen. Therefore,
One molecule of hydrogen = two atoms of hydrogen
12 molecules (one dozen) of hydrogen molecules = 12 × 12 = 24 atoms of hydrogen
And so, there are 24 atoms of hydrogen in ane dozen of hydrogen molecules. Now, one mole of hydrogen contains 6.022 × 10 23 of hydrogen atoms, that is 6.022 × 10 23 atoms of hydrogen = 1 mole of hydrogen
So, 24 atoms of hydrogen = 24 ( 6.022 × 10 23 ) moles of hydrogen atom
= 3.985 × 10 − 23 moles of hydrogen atom
Now the tooth mass of hydrogen is 1 g. This means that there are 6.022 × 10 23 atoms of hydrogen in 1 grand of hydrogen. As one mole of whatever substance contains 6.022 × 10 23 atoms, therefore
1g = 1 mole of H atom
Now equally the molar mass of H 2 molecule is 2g, therefore
two g of H 2 molecule = 1 mole of H ii molecule
ane thou of H 2 molecule = ( 1 2 ) mole of H 2 molecule
24 g of H 2 molecule = ( 24 2 ) mole of H ii molecule
= 12 moles of H ii molecule.
