Direction : In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:
Assertion : Number of gram-molecules of SO2Cl2 in 13.5 g of sulfuryl chloride is 0.1.
Reason : Gram molecular mass is equal to one gram molecule.
  • a)
    Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
  • b)
    Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).
  • c)
    Assertion (A) is true but reason (R) is false.
  • d)
    Assertion (A) is false but reason (R) is true.
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
Direction : In the following questions, a statement of assertion (A) ...
Gram molecular mass of, SO2Cl2 = 1 g molecule
135 g of SO2Cl2 = 1 g molecule [Since, GMM of SO2Cl2 = 135 g]
13.5 g of SO2Cl2 = 13.5/135 = 0.1 g molecule.

Direction : In the following questions, a statement of assertion (A) ...
Assertion: Number of gram-molecules of SO2Cl2 in 13.5 g of sulfuryl chloride is 0.1.
Reason: Gram molecular mass is equal to one gram molecule.

Explanation:
- The gram molecular mass of a substance is the mass of one mole of that substance. It is equal to the sum of the atomic masses of all the atoms in the molecule.
- The molar mass of SO2Cl2 can be calculated by adding the atomic masses of sulfur (S), oxygen (O), and chlorine (Cl).
- The atomic masses of S, O, and Cl are 32 g/mol, 16 g/mol, and 35.5 g/mol, respectively.
- Therefore, the molar mass of SO2Cl2 is (32 + 2 * 16 + 2 * 35.5) g/mol = 135 g/mol.
- Now, to find the number of gram-molecules of SO2Cl2 in 13.5 g, we divide the given mass by the molar mass.
- Number of gram-molecules = 13.5 g / 135 g/mol = 0.1 mol.
- Hence, the assertion is true.

Explanation of Reason:
- The reason provided is correct as the gram molecular mass is indeed equal to one gram molecule.
- A gram molecule is the amount of a substance that has a mass numerically equal to its molecular mass in grams.
- Therefore, the number of gram-molecules is equal to the mass of the substance in grams divided by its molecular mass in grams per mole.
- Hence, the reason is the correct explanation of the assertion.

Conclusion:
- Both the assertion and the reason are true, and the reason correctly explains the assertion.
- Therefore, the correct answer is option 'A'.
