Question

What is molecular formula?

Answer 1

Molecular formula:

• The molecular formula represents the actual number of atoms of each element present in a molecule.
• Example:- The molecular formula of $\mathrm{Ammonia}\mathrm{gas}\mathrm{is}{\mathrm{NH}}_3.$
• This shows that one molecule of ammonia gas contains $\mathrm{One}\mathrm{atom}\mathrm{of}\mathrm{Nitrogen}\left(\mathrm{N}\right)\mathrm{and}3\mathrm{atoms}\mathrm{of}\mathrm{Hydrogen}\left(\mathrm{H}\right).$
