WebJun 9, 2024 · In that case a dozen is 12 so \(12 \times 2 = 24\) hydrogen atoms in a dozen water molecules. To get the answers (4 and 24), you had to multiply the given number of molecules by two atoms of hydrogen per molecule. So to find the number of hydrogen atoms in a mole of water molecules, the problem could be solved in a similar manner. WebA mole of any substance is 6.022×1023 molecules. The Mole concept is one of the most convenient ways of expressing the amount of reactants and products in the reaction. The value of Avogadro’s number is approximately 6.022×1023. The definition of Avogadro’s number is that it tells us the number of particles in 1 mole (or mol) of a substance.
