A chemical formula that shows the actual and kinds of a atoms present in one molecule of compound is called
Correct answer: B. Molecular formula
- A. Empirical formula
- B. Molecular formula
- C. Ionic formula
- D. Covalent formula
Explanation
The molecular formula provides information about the elements present in the compound and their respective ratios. It represents the true composition of a molecule by indicating the specific number of atoms of each element in the compound. For example, C2H2, its molecular formula is also C2H2 showing that there are two carbon and 2 hydrogen atoms in each molecule of acetylene.

About Fundamental Concepts of Chemistry
Mole calculations connect mass, number of particles and Avogadro's number, while balanced equations provide the mole ratios used in stoichiometry. Questions cover limiting and excess reactants, theoretical yield and percentage yield, including identifying which reactant is consumed first and comparing the actual product with the maximum possible product.
