3.5 g CH4 x 1 mole/16 g x 6.02x10^23 molecules/mole x 4 H atoms/molecule = answer.
8 grams. Or more exactly, in 30.0 grams of methane there is 7.54 grams of hydrogen.
45,0 grams of hydrogen gas have 135,5.10e23 atoms.
1,204428358.1023 atoms of hydrogen
the chemical formula of methane is CH4. one molecule of methane contains one carbon atom and four hydrogen atoms.

Methane (CH4) has four atoms of hydrogen per molecule. If there are 3 moles of methane, then there are 12 moles of hydrogen.
carbon is one atom and hydrogen is four atoms in the methane totally 5 atoms in that.
The formula for methane is CH4, indicating 1 carbon atom and 4 hydrogen atoms.
The hydrogen molecule contains 4 Hydrogen atoms, and one Carbon in the centre.
Well methane has a chemical structure of CH4 (one carbon surrounded by 4 hydrogen atoms), so for 2 methane you would need a total of 2 carbon atoms and 8 hydrogen atoms (or 4 H2 molecules)
The molecule of methane has 5 atoms.
