The formula of a substance is the symbolic representation of a chemical substance.
To write the formula of a chemical substance, the valency and the symbol of the various atoms or radicals present in it must be known.
The chemical formula represents the name of the compound, elements constituting the compound and the molecular weight of the compound, and the relative weights of different elements present in it.
For example, the chemical formula of sulphuric acid is [tex]H_2SO_4 \: [/tex]
The formula of a compound represents the elements that make up the compound and the number of atoms of each element. It is a shorthand way of writing the chemical composition of a compound.
For example, the formula for water is H2O. This tells us that water is made up of two hydrogen atoms and one oxygen atom. The subscript 2 after the hydrogen atom tells us that there are two hydrogen atoms, and the subscript 1 after the oxygen atom tells us that there is one oxygen atom.
The formula of a compound can be written in a few different ways. The most common way is to use the chemical symbols for the elements and the subscripts to indicate the number of atoms of each element. However, the formula can also be written using words. For example, the formula for water can also be written as "hydrogen monoxide."
The formula of a compound is a very important part of chemistry. It is used to identify compounds, to calculate the mass of a compound, and to predict the properties of a compound.
Here are some additional things to keep in mind about the formula of a compound:
* The formula of a compound must be balanced. This means that the number of atoms of each element in the formula must be equal to the number of atoms of that element in the compound.
* The formula of a compound can be used to calculate the molar mass of the compound. The molar mass is the mass of one mole of the compound.
* The formula of a compound can be used to predict the properties of the compound. For example, the formula of water tells us that water is a polar molecule.
