Given mass is 20g number of moles of SO3 =20/80=0.25. Number of molecules =0.25*6.023*10^23
=1.5*10^23.
number of atoms 4.
so finaly total number of atoms =4*1.5*10^23=6*10^23.
=1.5*10^23.
number of atoms 4.
so finaly total number of atoms =4*1.5*10^23=6*10^23.

The number of molecules will be (6.022 *10 ^ 23 )/ 4 or 1.5055*10^23. And no of atoms will be same that 6.022*10^23.
