So, 1 mole H2O = 1.2044X10^24 hydrogen atoms. Therefore 2 mole H2O will have 2.4088X10^24 hydrogen atoms. Since one mole is defined as 6.022 x 10^23, and there are two hydrogen per molecule, that would mean that there are exactly 12.044 x 10^23 molecules of hydrogen in one mole of water.

A mole is a unit used in chemistry to represent a specific number of particles, which is approximately 6.022 x 10^23 particles. In the case of water molecules (H2O), 1 mole of water molecules contains this enormous number of water molecules.
To determine the number of atoms in a mole of water molecules, we need to consider the composition of a water molecule. A water molecule consists of two hydrogen atoms (H) and one oxygen atom (O). Therefore, we have:
- 2 moles of hydrogen atoms: Since each water molecule contains 2 hydrogen atoms, 1 mole of water molecules will contain 2 moles of hydrogen atoms. This is because the mole ratio of hydrogen atoms to water molecules is 2:1.
- 1 mole of oxygen atoms: Each water molecule contains 1 oxygen atom. Therefore, in 1 mole of water molecules, there will be 1 mole of oxygen atoms.
Hence, the correct option is C, which states that 1 mole of water molecules has 2 moles of hydrogen atoms.
