1 mol ------------- 6.02x10²³ atoms
1.14 moles ------ ( atoms )

atoms = 1.14 x ( 6.02x10²³) / 1

atoms = 6.86 x 10²³ / 1

=  6.86 x 10²³ atoms

hope this helps!

NA = 6.02210^23
number of atoms = number of moles avogadros number
number of atoms = 6.02210^23 1.14 moles * 4 atoms / molecules of SO3
Number of atoms = 2.75×10^24 atoms.
