Problem:
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

Solution:

Maximum number of moles have maximum number of molecules
So, we will calculate number of moles for each of these.
8 g H₂ = $\frac{8}{2}$ = 4 moles

44 g of CO₂= $\frac{44}{44}$ = 1 mole
64 g SO₂ = $\frac{64}{64}$ = 1 mole

48 g of O₃ = $\frac{48}{48}$ = 1 mole

Option (a) is correct
