=0.1075*10^23=0.10751023 molecules of SO_2SO2

Explanation:

We know1 mole or 6.022*10^236.0221023 molecules of SO_2SO2 occupies 22.4 L at STP
So at STP 1L will contains 6.022/22.4*10^236.02222.41023 molecules of SO_2SO2
:.At STP 0.4L will contains 6.022/22.4*0.4*10^23=0.1075*10^23 molecules of SO_2
