Answer: There are 20.0 moles of hydrogen atom in 5.0 moles of methane.
Explanation:
We are given:
Moles of methane = 5.0 mol
The chemical formula for methane is [tex]CH_4[/tex]
By Stoichiometry:
in 1 mole of methane there are 4 moles of hydrogen atom.
So, moles of hydrogen atom in 5.0 mol of methane will be :
[tex]5.0\times 4 mol=20.0mol[/tex]
Hence, there are 20.0 moles of hydrogen atom in 5.0 moles of methane.
