Final answer:
The question pertains to the concept of a mole in Chemistry. Specifically, a mole relates to Avogadro's number, 6.02 x 10^23. In the case of one mole of H2O, because one molecule of water contains 2 hydrogens and 1 oxygen, one mole of H2O would consist of 3 * 6.02 x 10^23 total atoms.
Step-by-step explanation:
The subject of your question involves a concept in Chemistry, specifically the idea of a mole. One mole is defined as being equivalent to the quantity 6.02 x 10^23, which is also known as Avogadro's number. Therefore, if you're referring to one mole of H2O (i.e. water), remember that a single water molecule consists of three atoms: 2 hydrogens (H) and 1 oxygen (O). Thus, one mole of H2O actually contains three times the Avogadro's number of atoms, or 3 * 6.02 x 10^23 atoms in total.
