Answer:

believe it is D

Assuming ideal gas then PV = nRT

At same P and T then it becomes V = nR and R is constant meaning V = n.

As n = moles = mass/molar mass then lower molar mass is higher n as mass is constant:

ethane molar mass = C2H6 = 30

oxygen molar mass = O2 = 32 (diatomic)

fluorine molar mass = F2 = 38 (diatomic)

neon molar mass = N = 20
