Answer 2

Answer: B. A molecular formula gives only the number and kind of atoms present in a molecule

Explanation: A molecular formula is the chemical formula of a substance which gives the actual number of atoms of each element present in the substance. It tells nothing about the size and shape of the atoms contained in it.

Empirical formula gives the simplest ratio of the atoms of each element present in the substance.

For example : The molecular formula of benzene is $C_6H_6$ which gives the actual number of atoms of each element present and the empirical formula of benzene is $CH$ which gives the simplest ratio of atoms present in it.
