Question

The number of electrons in a mole of hydrogen molecule is

(a) 6.02×10²³
(b) 3.0115×10²³
(c) 3 0155×10²³
(d) indefinite

Answer 1

heya!

here is your answer


one mole hydrogen moleculecontains 2X6.022X1023 atoms = 12.044 X 1023 atoms. So total electron in one mole of hydrogen is 12.044X1023.

Answer 2

Explanation:

Atomic number of hydrogen is 1 and its electronic configuration is $1s^{1}$. Therefore, in two atoms of hydrogen there are two electrons.

According to Avogadro's number, number of atoms in one mole of a substance is $6.02 \times 10^{23}$.

Thus, number of electrons in a mole of hydrogen molecule is as follows.

                $2 \times 6.02 \times 10^{23}$

             = $12.04 \times 10^{23}$

Hence, we can conclude that there are $12.04 \times 10^{23}$ number of electrons in a mole of hydrogen molecule.
