In each of the following question, an Assertion (A) is following by a corresponding Reason (R ). Use the following keys to choose the appropriate answer.
Assertion : 1 amu equals to `1.66xx10^(-24) g`.
Reason : `1.66xx10^(-24) g` equals `1"/"12`th mass of `C^(12)` atom.

A

If both (A) and ( R ) are correct and ( R ) is the correct explanation of (A).

B

If both (A) and (R ) are correct, but ( R ) is not the correct explanation of (A).

C

If (A) is correct, but ( R) is incorrect.

D

If both (A) and (R ) are incorrect.

Text Solution

Verified by Experts

The correct Answer is:
A
`12 g C-12` contains `6.02xx10^(23)` atom, `.:" " 1" amu "=(1)/(12)xx(12)/(6.02)xx10^(-23)=1.66xx10^(-24)g`
