~~~~~~~~~~~
in the formula. It also represents the number of molecules of that compound. has 4 sodium atoms, 2 sulphur atoms, and 8 oxygen atoms. When you count atoms, remember to multiply the coefficient number and the subscript number to find the number of atoms of that element.

Answer: AIP
There are two types of substances mixture and pure substance. Mixture has NO chemical formula and a pure substance has a chemical formula. There are two types of pure substances, elements (mono atomic and molecular) and compounds ( covalent and ionic).
Ionic compounds do not exist in independent molecular form. They form three dimensional crystal lattice, in which each ion is surrounded by oppositely charged ion. so the ratio of ion is called the formula unit
