Question

how many atoms of hydrogen in 1gm H2 gas?

Answer 1

Heya friend,


Here is your answer,

Well an hydrogen atom has a molar mass of about 1g⋅mol−1.

Therefore,

A 1g of sample contains 1mol of hydrogen atoms

1 mol = 6.022×10^23 atoms

Therefore,

There are 6.022×10^23 of hydrogen atoms in 1 g of H2 gas.



Hope it helps you.
Thank you.

❇️❇️❇️❇️❇️❇️

⏭️⏭️A H2 molecule has a molar mass of 2 g ⋅ m o l − 1 . You get this molar mass by adding up the molar masses of all the atoms in the molecule. Each hydrogen molecule contains 2 hydrogen atoms, therefore the sample contains 6.02 × 10 23 atoms.
