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.
the chemical formula of methane is CH4. one molecule of methane contains one carbon atom and four hydrogen atoms.

To calculate the number of atoms in 3.4 grams of hydrogen peroxide, you first convert the grams to moles using the molar mass of hydrogen peroxide. Then, you use Avogadro's number to convert moles to atoms. There are approximately 6.022 x 10^23 atoms in 1 mole of a substance.
8 grams. Or more exactly, in 30.0 grams of methane there is 7.54 grams of hydrogen.
The molecule of methane has 5 atoms.
45,0 grams of hydrogen gas have 135,5.10e23 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.
4, as indicated by the subscript on the symbol for hydrogen in the formula for methane, CH4.
One methane molecule contains one carbon atom and four hydrogen atoms.

The hydrogen molecule contains 4 Hydrogen atoms, and one Carbon in the centre.
the chemical formula of methane is CH4. one molecule of methane contains one carbon atom and four hydrogen atoms.
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)
