How many atoms of hydrogen are in two moles of ch4?

There are four Hydrogen atoms in one molecule of Methane (CH₄).

And there are 6.022*10²³ molecules in 1 mole of CH₄.

So,

Number of Hydrogen atoms is 1 mole of CH₄ are,

= 6.022 * 10²³ * 4

= 2.4 * 10²⁴ Hydrogen Atoms

Now calculating for 2 moles,

As,

1 mole of CH₄ contains = 2.4 * 10²⁴ Hydrogen Atom

Then,

2 moles of CH₄ will contain = X Hydrogen Atoms

Solving for X,

X = (2 moles * 2.4 * 10²⁴ Hydrogen Atom) : 1 mole

X = 4.8 * 10²⁴ Hydrogen Atoms
