Assertion (A): Both `138 g` of `K_(2)CO_(3)` and `12 g` of carbon have some number of carbon atoms.
Resaon (R ): Both contains `1 g` atom of carbon which contains `6.022 xx 10^(23)` carbon atoms.

A

If both (A) and (R ) are correct and (R ) is the correct explantion for (A)

B

If both (A) and (R ) are correct but (R ) is not the correct explantion for (A)

C

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

D

If (A) and (R ) are incorrect.

Text Solution

Verified by Experts

The correct Answer is:
A
`138 g K_(2)CO_(3) = 1 "mol" -= 1 g` atoms of `C`.
`12 g C = 1 g` atom of `C`
