If 1 Nm3 of O2 contains 'N' number of molecules, then number of molecules in 2Nm3 of SO2 will be_________________?
Correct answer: D. 2N
- A. N
- B. N/2
- C. 4N
- D. 2N
Explanation
At the same reference conditions, equal gas volumes contain equal numbers of molecules according to Avogadro’s law. Thus 2 Nm³ of SO₂ contains twice the molecules in 1 Nm³ of O₂, or 2N.
