Assertion: Both `12 g`. of carbon and `27 g`. of aluminium will have `6.02xx10^(23)` atoms.
Reason: Gram atomic mass of an element contains Avogadro's number of atoms.

A

Both Assertion and Reason are true and Reason is the correct explanation of Assertion

B

Both Assertion and Reason are true but Reason is not a correct explanation of Assertion

C

Assertion is true but Reason is false

D

Assertion is false but Reason is true

Text Solution

Verified by Experts

The correct Answer is:
A
12g of C contains `6.023xx10^23` atoms and 27 g of Al also contains `6.023xx10^23` atoms . These two are gram atomic masses of carbon and aluminium respectively, hence , reason is a correct explanation for assertion.
