What is the number of moles of Cl atoms present in n moles of tear gas and in n moles of mustard gas respectively?

Options

  1. A2n and 3n
  2. B3n and 2n
  3. Cn and 3n
  4. Dn and 2n

Correct answer

B. 3n and 2n

Step-by-step solution

The chemical formula of tear gas (chloropicrin) is CCl₃NO₂ . One molecule of tear gas contains 3 chlorine atoms. Therefore, n moles of tear gas contain 3n moles of Cl atoms. The chemical formula of mustard gas is S(CH₂CH₂Cl)₂ . One molecule of mustard gas contains 2 chlorine atoms. Therefore, n moles of mustard gas contain 2n moles of Cl atoms. Answer: 3n and 2n
