To answer this, we need to convert these values into number of moles by the use of the relationship of moles and liters at STP. Do as follows:A. 0.520 L SO3 ( 1 mole / 22.4 L) = 0.023 molB. 0.10 L Xe ( 1 mol / 22.4 L) = 0.004 molC. 7.0 LN2 ( 1 mol / 22.4 L) = 0.31 mould. 12.0 L Ne ( 1 mol / 22.4 L) = 0.54 molTherefore, option D is the answer.
