    24 atoms of H or 1.4 x 10²⁵ hydrogen atoms

    Explanation:

    simple method

    1 H₂O has atoms of hydrogen and 1 atom of oxygen

    while 12H₂O will have 24 atoms of hydrogen and 12 atom of oxygen

    by Avagadros number

    molar mass of water H₂0=18.01528 g/mol

    1 mole of H₂0 have 2 moles of Hydrogen

    one mole of water = 6.02⋅10²³water molecules = 1.2 x 10²⁴hydrogen atoms

    12 mole of H₂O = 1.2 x 10²⁴ x 12 = 1.4 x 10²⁵ hydrogen atoms

    1.4 x 10²⁵ hydrogen atoms in 12 moles of H₂O
