... Hint: According to the chemical formula, one mole of CH4 contains 1 mole of C atoms and 4 moles of hydrogen atoms. Thus, the mole of H = 4 x {mass of CH4/molar mass of CH4}. When converting moles into atoms, it needs to multiply the Avogadro’s number, that is, 6.02x1023. Thus the number of H atoms = ...
