Question

12. Assertion: Both 32 g of SO2 and 8 g of CH4 contain the same number of molecules.
Reason: Equal moles of two compounds contain the same number of molecules.
a. Both assertion and reason are CORRECT and reason is the CORRECT explanation
of the assertion.
b. Both assertion and reason are CORRECT but, reason is NOT THE CORRECT
explanation of the assertion.
c. Assertion is CORRECT but, reason is INCORRECT.
d. Assertion is INCORRECT but, reason is CORRECT.​

Answer 1

Given:

Assertion: Both 32 g of SO2 and 8 g of CH4 contain the same number of molecules.

Reason: Equal moles of two compounds contain the same number of molecules.  

To find:

Where both the assertion and reason are valid or not.

Solution:

From given, we have,

Assertion: Both 32 g of SO2 and 8 g of CH4 contain the same number of molecules.

Reason: Equal moles of two compounds contain the same number of molecules.  

The number of moles of SO2 = given weight /molar mass = 32/64 = 1/2 mole

The number of moles of CH44 = given weight /molar mass = 8/16 = 1/2 mole

Option a. Both assertion and reason are CORRECT and the reason is the CORRECT explanation of the assertion is correct.

Answer 2

Answer:

both assertion and reason are correct and reason is a correct explanation of assertion
