4g of NH3 Explanation: Molecular mass of O2 = (2 x 16) = 32 g Molecular mass of NH3 = 14 + (3 x 1) = 17 g (least weight) Molecular mass of CO2 = 12 + (2 x 16) = 44 g Molecular mass of SO2 = 32 + (2 x 16) = 64 g $\therefore$ 4 g of NH3 contains = (6.02 xx 10^23)/17 xx 4 = 1.41 x 1023 $\therefore$ 4 g of NH3 having minimum molecular mass contain maximum molecules.
