There are 5.1034 ×[tex]10^{11}[/tex] molecules.
A molecule, which consists of two or more atoms connected by chemical bonds, is the smallest unit of a substance that retains its composition and physical characteristics. Moles are the basic units of chemistry. To distinguish between elements and molecules, an atom count subscript is added after the element symbol.
For instance, the oxygen molecule (O2) is homonuclear because it contains two atoms. In contrast, a molecule can also be heteronuclear, which is a chemical compound made up of many elements, like water (two hydrogen atoms and one oxygen atom; H2O). The term "molecule" is used frequently in the kinetic theory of gases to refer to any gaseous particle, regardless of its chemical makeup.
