To answer this, we have to convert these values into number of moles by using the relation of moles and liters at STP. We do as follows:

A. 0.520 L SO3 (1 mol / 22.4 L) = 0.023 mol

B. 0.10 L Xe (1 mol / 22.4 L) = 0.004 mol

C. 7.0 LN2 (1 mol / 22.4 L) = 0.31 mol

D. 12.0 L Ne (1 mol / 22.4 L) = 0.54 mol

Therefore, option D is the answer.
