Which one of following could be the molecular formula of vitamin A? Options C20H30O , C12H18N4Cl2OS, C17H20N4O6, C9H17O5N.

C12H30O

Vitaman.a has a molecular formola c20h30o . The number of vitaman .a molecules in 500 mg of its capsule will be

To determine the molecular formula of vitamin A, we need to understand its chemical composition.

Vitamin A is a fat-soluble vitamin that belongs to a group of organic compounds called retinoids. It is derived from a compound called retinol, which is an alcohol form of vitamin A. The molecular formula of retinol is C20H30O, so it is not one of the provided options.

Let's examine the other options:

1. C12H18N4Cl2OS: This formula does not match the molecular formula of vitamin A.

2. C17H20N4O6: This formula also does not match the molecular formula of vitamin A.

3. C9H17O5N: This formula does not match the molecular formula of vitamin A.

Therefore, none of the provided options match the molecular formula of vitamin A. The correct molecular formula for vitamin A is C20H30O.
