If we are given the mass of a substance ,we can calculate the _ of the other substance with the help of a balanced chemical equation:
Correct answer: D. All of these
- A. Mass
- B. Volume
- C. Moles
- D. All of these
Explanation
Option D is correct as with the "mass" of a substance and the balanced equation of a reaction with that substance, we can calculate the "moles" of all other reactions participatingsubstances from which we can find their "masses" and "volumes".

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.
