In the gaseous state, the distance between the molecules is _ than their diameters:
Correct answer: C. 300 times greater
- A. 200 times lesser
- B. 300 times less
- C. 300 times greater
- D. 200 times greater
Explanation
In the gaseous state the distance between the molecules is 300 times greater than their diameters. In the gaseous state, molecules move freely and rapidly, and the distance between them is much larger compared to the size of the molecules themselves. The actual distances between gas molecules can vary, but they are typically on the order of several times the diameter of the molecules.

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.
