How many atoms of hydrogen are in two moles of ch4?
ziro4ka [17]
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
