To determine which of the listed molecules contains two atoms of hydrogen (H), we can analyze each option:
1. **2H2O (2 water molecules)** - Each water molecule (H2O) contains 2 hydrogen atoms. Therefore, 2H2O contains \( 2 \times 2 = 4 \) hydrogen atoms.
2. **2CH4 (2 methane molecules)** - Each methane molecule (CH4) contains 4 hydrogen atoms. Therefore, 2CH4 contains \( 2 \times 4 = 8 \) hydrogen atoms.
3. **HO2 (hydrogen peroxide)** - This molecule contains only 1 hydrogen atom and 2 oxygen atoms. So, it contains 1 hydrogen atom.
4. **H2SO4 (sulfuric acid)** - This molecule contains 2 hydrogen atoms, along with 1 sulfur and 4 oxygen atoms.
Out of all the options presented, **H2SO4** is the only molecule that contains exactly two atoms of hydrogen.
