Question

Assertion :One mole of oxygen gas occupies 22.4 l volume at STP. Reason: Volume of a gas depends on temperature and pressure and also nature of gas.
  1. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
  2. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
  3. Assertion is correct but Reason is incorrect
  4. Both Assertion and Reason are incorrect

A
Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
B
Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
C
Assertion is correct but Reason is incorrect
D
Both Assertion and Reason are incorrect
Solution
Verified by Toppr

1 mole of any gas occupies 22.4 l at STP.

Therefore, 1 mole of O2 occupies 22.4 l at STP.

Thus the assertion is correct.

The volume of gas depends upon temperature, pressure, no. of moles present but not on the nature of the gas.

Thus the reason is incorrect.
