Question

Which one of the following gas contains the same number of molecules as 16 g of oxygen?

(a) 16 g O₃

(b) 16 g SO₂

(c) 32 g SO₂

(d) All the above

Answer 1

Correct option is (c) 32 g SO₂

16 g of O₂ = \(\frac{16}{32}\) = 0.5 moles

16 of SO₂ = \(\frac{16}{64}\) = 0.25 moles

32 g of SO₂ = \(\frac{32}{64}\) = 0.5 moles
