Interpretation:
The total number of moles of atoms that is present in
Concept Introduction:
Chemical formula of a substance can be interpreted in two different ways, namely, in microscopic-level and macroscopic-level. Chemical formula at microscopic-level can be said as the one that indicates the number of atoms of different elements that is present in a formula unit or one molecule of substance. The numerical value present in subscripts in a chemical formula indicates the number of atoms of various elements that is present in one formula unit of substance.
In macroscopic-level the chemical formula of a substance indicates the number of moles of atoms of different elements that is present in one mole of a substance.
Conversion factors which relate a component of a substance to the substance as a whole are dependent on the chemical formula of the substance.
