Two flasks A and B of 1 L capacity each contain SO₂ and Br₂ gases respectively, maintained at 340 K — States of Matter and Gaseous State Chemistry Question
Question
Two flasks A and B of 1 L capacity each contain SO₂ and Br₂ gases respectively, maintained at 340 K and pressure of 1.5 atm. If number of Br₂ molecules in flask B is N, the total number of atoms in flask A will be

Answer: D
💡 Solution & Explanation
Same T, P, V → same number of molecules. Flask A has N molecules of SO₂. Each SO₂ has 3 atoms → total atoms = 3N.
