For the reaction A + 2B → C, 5 moles of A and 8 moles of B will produce how many moles of C?
Correct answer: C. 4 moles of C
- A. 5 moles of C
- B. 8 moles of C
- C. 4 moles of C
- D. 13 moles of C
Explanation
First, identify the limiting reactant. Since 8 moles of B would only require 4 moles of A, B is the limiting reactant. The amount of product is determined by the limiting reactant; since the ratio of B to C is 2:1, 8 moles of B will produce 4 moles of C.

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.
