Number of covalent bonds in 10 mol of carbon tetrachloride is
Correct answer: A. 2.4 x 10 ^25
- A. 2.4 x 10 ^25
- B. 40
- C. 4 x 10 ^24
- D. 6.4 x 10 ^21
Explanation
The number of covalent bonds in 10 moles of carbon tetrachloride (CCl4) can be calculated as follows:One molecule of CCl4 contains four covalent bonds .One mole of CCl4 contains Avogadro's number of molecules, which is approximately 6.022 x 10^23 2.Therefore, 10 moles of CCl4 contains 10 x Avogadro's number of molecules, which is approximately 6.022 x 10^24 Multiplying the number of molecules by the number of covalent bonds per molecule, we get:Number of covalent bonds=6.022×10^24 molecules×4 covalent bonds per molecule=2.4088×10^25 covalent bondsTherefore, the answer to your question is a. 2.4 x 10^25.

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.
