Question

What is the number of hydrogen atoms in 1 mole of methane (CH4)?

Answer 1

1 mole of methane contains 4 moles of hydrogen.
1 mole of Hydrogen = 6.022 x 10^23 Atoms
4 moles = 4 x 6.022 x 10^23
= 24.088 x 10^23 atoms

Answer 2

Answer: The number of hydrogen atoms in given moles of methane are $24.088\times 10^{23}$

Explanation:

We are given:

A chemical compound having chemical formula of $CH_4$

In 1 mole of methane molecule, 1 mole of carbon atom and 4 moles of hydrogen atoms are present.

According to mole concept:

1 mole of compound contains $6.022\times 10^{23}$ number of atoms

So, 1 mole of methane molecule will contain = $4\times 6.022\times 10^{23}=24.088\times 10^{23}$ number of hydrogen atoms.

Hence, the number of hydrogen atoms in given moles of methane are $24.088\times 10^{23}$
