Calculate the number of atoms in 1.0 mole of O2. Elemental Form of Oxygen: Oxygen appears as a diatomic molecule in its elemental form. In the diatomic molecule, two oxygen atoms remain attached together by a double bond. In normal atmospheric pressure and temperature, oxygen exists as a gase...
To find the number of oxygen atoms in one gram equivalent of oxygen, we will follow these steps:Step 1: Understand the concept of gram equivalent A gram equivalent (g-equivalent) is defined as the amount of substance that will
