the number of oxygen atoms in each oxygen molecule
The subscript in O₂ signifies the number of oxygen atoms in each oxygen molecule.
An atom is the smallest indestructible particle that takes part in chemical reactions.
Molecules are combinations of atoms. They are usually formed when two atoms combines and shares their valence electrons to form covalent bonds.An oxygen molecule O₂ is made up of two oxygen atoms. The oxygen atoms are held by covalent bonds. The 6 coefficient denotes the volume or number of molecules.
The answer is the number of oxygen atoms in each oxygen. This is a common SI standard for writing empirical formula for chemical compounds and their reactions. In compounds, the superscript is used to indicate the number of atoms of an element in the compound. For example, in this case, one oxygen molecule has two oxygen atoms. Therefore 6 oxygen molecules have (6*2) 12 oxygen atoms. The number in front represents the number of molecules of the compound or element.
Since O₂ has two oxygens, there are two atoms. After converting grams to molecules, multiply the amount of molecules you have by two.
Mass of oxygen given = 35.5 g
Molecular mass of oxygen = 32 g/mole.
