How many seconds would it take to spend one Avogadro number of rupees at a rate of 6.02 x 10^9 rupees per second?
Correct answer: C. I x 1014
- A. 19 x 10^9
- B. 19 x 10^10
- C. I x 1014
- D. 2 x 10^11
Explanation
Option C is correct. Avagadro number(NA) = 6.02 x 1023 rate = 6.02 x 109 rupees per second time to spend NA rupees = 6.02 x 1023 / 6.02 x 109 = 1 x 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.
