Which of the following gases contains the least number of atoms at s.t.p?
- 1 mole of butane
- 3 mole of ozone
- 4 mole of chlorine
-
7 mole of argon
The correct answer is: 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.
