Question

Which of the following pair contains gases heavier than N2?
(a) CO, SO2
(b) He, Ne
(c) He, H2
(d) Ne, H3​

Answer 1

Answer:

co, so2

Explanation:

N2- mass is 28 u

whereas mass of CO is 28 u

and mass of SO2 is 64 u

Answer 2

Option(a)  -  CO , SO₂

• The molecular mass of N₂ is 28 u
• The molecular mass of CO is 28 u
• The molecular mass of SO₂ is 64 u

Therefore, CO , SO₂  is the pair the contains gases heavier than  N₂
