What are the number of covalent bonds in 68 g of H2S gas?
Correct answer: C. 2.41 x 10^24
- A. 3.01 x 10^23
- B. 6.02 x 10^23
- C. 2.41 x 10^24
- D. 2.24 x 10^24
Explanation
Moles of H2S=mass/molar mass= 68/43= 2 moles Number of molecules= moles( NA) =2(6.02 x 1023) Number of covalent bonds=2( number of molecules) = 2.41 x1024 covalent bonds.So option C is correct.

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.
