The molecular formula of a compound provides important information about the composition of the compound. It represents the actual number of different types of atoms present in a molecule of the compound. Let's understand why option 'A' is the correct answer in more detail:
Exact Number of Different Types of Atoms:
The molecular formula gives us the exact number of each type of atom present in a molecule of the compound. For example, the molecular formula of water is H2O, which indicates that there are two hydrogen atoms (H) and one oxygen atom (O) in each water molecule. The subscript numbers in the formula represent the number of each type of atom.
Whole Number Ratio of Different Types of Atoms:
While the molecular formula shows the exact number of atoms, it also provides information about the whole number ratio of different types of atoms. In the case of water, the ratio of hydrogen to oxygen atoms is 2:1. This means that for every two hydrogen atoms, there is one oxygen atom.
Ratio of Masses of Various Atoms:
Although the molecular formula does not directly provide the ratio of masses of various atoms, it indirectly gives us information about the relative masses. Each atom has a specific atomic mass, and by knowing the number of atoms in a molecule, we can calculate the total mass of the molecule. This information can be used to determine the ratio of masses of the different atoms present in the compound.
Average Decimal Ratio of Various Atoms:
The molecular formula does not give us the average decimal ratio of various atoms. The average atomic mass of an element is calculated by considering the isotopic abundance of each isotope. This information is not provided by the molecular formula.
In conclusion, the molecular formula of a compound shows the exact number of different types of atoms present in a molecule of the compound. It also indirectly provides information about the whole number ratio of different types of atoms and can be used to calculate the total mass of the molecule. Therefore, option 'A' is the correct answer.
