How many seconds would it take to spend one Avogadro number of rupees at a rate of 6.02 x 10⁹ rupees per second?
Correct answer: C. 1 x 10¹⁴
- A. 1.9 x 10⁹
- B. 1.9 x 10¹⁰
- C. 1 x 10¹⁴
- D. 2 x 10¹¹
Explanation
To find the time, divide the total amount (Avogadro's number, ~6.02 × 10²³) by the rate of spending. Time = (6.02 × 10²³ rupees) / (6.02 × 10⁹ rupees/s) = 1 × 10¹⁴ seconds.

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.
