The hydrogen and oxygen<span> atoms from H</span>₂O are <span>bonded together through covalent </span>bonding.
The number of atoms of oxygen is 2.4 * 10^24.
<h3>How many atoms are produced?</h3>
We know that mole of a substance contains the Avogadro's number of atoms. The Avogadro's number gives the number of atoms, molecules, ions and atoms that could be found in one mole of a substance.
Now;
Given that ;
1 mole of oxygen contains two atoms of oxygen, the number of atoms that are contained in 2 moles of the oxygen molecule is;
2 * 2 * 6.023 * 10^23
= 2.4 * 10^24
