Question

What is the molecular formula of vinegar?

Answer 1

The molecular mass is a formula which consists of the chemical symbols for the elements the molecule is made up of following the numeric subscript which describes the number of atoms of that element in the molecule.

Complete step by step answer:
Vinegar is also known as acetic acid or ethanoic acid.
Acetic acid is a synthetic carboxylic acid with antibacterial and antifungal properties.
It belongs to the carboxylic acid group.
Acetic acid or ethanoic acid is a weak acid which can inhibit carbohydrate metabolism which can result in death of an organism.
It is a glacial liquid that appears as a clear colorless and has a strong odor of vinegar.
It is corrosive to metals and tissues.
It is used to make other chemicals, food preservative and in petroleum production.
It is a conjugate acid of an acetate.
It is a simple monocarboxylic acid used as a food acidity regulator, antimicrobial food preservative, also as a protic solvent.
‘Eth’ means it is composed of two carbon atoms since ‘eth’ means two or is abbreviated for two and here it means two carbon atoms.
So the formula comes out to be $C{{H}_{3}}COOH$.

Note: The given formula can also be written as ${{C}_{2}}{{H}_{4}}{{O}_{2}}$. The both means the same just written differently also known as the compressed form. If we don’t know the molecular formula which can be given it can also be calculated and in some cases we need to learn it.
