-
A.
1 mole of butane
-
B.
3 mole of ozone
-
C.
4 mole of chlorine
-
D.
7 mole of argon
Correct Answer: Option D
Explanation
Cl is diatomic; 4\(Cl_2\) = 8 atoms in total.
Oxygen is triatomic in Ozone; 3\(O_3\) = 9 atoms in total
Butane is \(C_4H_{10}\) = 14 atoms in total.
Argon is monoatomic; = 7atoms.
hence Option D is correct.
