Q. Which has the maximum number of molecules among the following?
A) 8 g H₂
B) 64 g SO₂
C) 44 g CO₂
D) 48 g O₃
Explanation
[Solution from source] Moles: 8 g H₂ = 8/2 = 4 mol; 64 g SO₂, 44 g CO₂ and 48 g O₃ are each 1 mol. The largest number of moles means the most molecules, so 8 g of H₂ has the most, even though it has the smallest mass. Answer (1).
