The formula that gives the symbolic representation of the actual number of atoms
The formula that gives the symbolic representation of the actual number of atoms of various elements present in one molecule of the compound, is called:
- A. molecular formula
- B. empirical formula
- C. molecular mass
- D. formula mass
Step-by-step solution
The molecular formula gives the exact number of atoms of each element in one molecule of a compound. The empirical formula provides the simplest whole-number ratio, molecular mass is the mass of a molecule, and formula mass refers to ionic compounds. Thus, the correct answer is molecular formula.
