Question

5. What is a molecular formula? Explain its significance using potassium nitrate as an example.​

Answer 1

Explanation:

The molecular formula is the expression of the number of atoms of each element in one molecule of a compound. The molecular formula definition is the formula showing the actual number of each atom in a molecule. When the molar mass value is known, the Molecular Formula is calculated by the empirical formula.

Potassium nitrate is a chemical compound with the chemical formula KNO3. It is an ionic salt of potassium ions K+ and nitrate ions NO3−, and is therefore an alkali metal nitrate. It occurs in nature as a mineral, niter.
