Chemistry · Some Basic Concepts of Chemistry

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Avogadro's law states that equal volumes of all gases under the same conditions of temperature and pressure contain equal number of molecules. Reason (R): Volume of a gas is directly proportional to the number of moles at constant temperature and pressure. In the light of the above statements, choose the correct answer from the options given below:

1. Both (A) and (R) are true and (R) is the correct explanation of (A).
2. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
3. (A) is true but (R) is false.
4. (A) is false but (R) is true.
