Question

Is $ {H_2}O $ an empirical formula?

Answer 1

Hint: Water is an inorganic, clear, tasteless, odourless, and virtually colourless chemical liquid that is the primary component of the Earth's hydrosphere and all known living creatures' fluids (in which it acts as a solvent). Even though it contains no calories or organic nutrients, it is necessary for all known forms of life. Each of its molecules has one oxygen and two hydrogen atoms linked by covalent bonds, as indicated by its chemical formula $ {H_2}O $ .

Complete answer:
The empirical formula of a chemical compound is the simplest positive integer ratio of atoms present in the molecule, as defined in chemistry. The molecular formulae, on the other hand, which indicate the number of atoms in each molecule of a chemical compound, are not identical.
The arrangement or number of atoms are not mentioned in an empirical formula. In contrast, the molecular formula indicates the number of each sort of atom in a molecule. The structural formula depicts the molecule's configuration. Different types of compounds can also have empirical formulae that are equivalent.
The empirical formula is the most basic whole-number ratio for defining a species' component atoms. $ {H_2}O $ is the empirical formula since it is the simplest whole number ratio.
To put it another way, the molecular formula is always a multiple of the empirical formula:
 $ M.F. = n\left( {E.F.} \right) $
where n is an integer.
Because the chemical formula of water is obviously $ {H_2}O $ , the multiple is 1.
Hence Yes is the answer.

Note:
Empirical formulas are the simplest forms of chemical formulae, and they utilise letters and numbers to indicate the numerical proportions of atoms of each type. The simple numbers of each kind of atom in a molecule are represented by molecular formulas, which include no structural information. The empirical formula for glucose, for example, is $ C{H_2}O $ (two times as many hydrogen atoms as carbon and oxygen), but the molecular formula is $ {C_6}{H_{12}}{O_6} $ (12 hydrogen atoms, six carbon and oxygen atoms).
