Question

find the number of atom present in 1mole of hydrogen gas​

Answer 1

Explanation:

However the question is asking for the amount of atoms in 1 mole of H2. Thus we must consider the makeup of an H2 molecule, where we see that it is a diatomic molecule. 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.

Answer 2

Given :-

Number of Mole = n = 1 mole

As we know that,

No. of atoms = n × A

Here, A is the Avogadro's number.

As, Hydrogen gas is a diatomic atom. It means in atmosphere hydrogen gas is found in ${H}_{2}$ form.

No. of atoms = 2 × 1 × 6.022 × 10²³ atoms

No. of atoms = 12.044 × 10²³ atoms.

No. of atoms = 1.2044 × 10²⁴ atoms.
