Question

How many atoms are in 1.14 mol so3?

Answer 1

NA = 6.022*10^23
number of atoms = number of moles * avogadros number
number of atoms = 6.022*10^23 * 1.14 moles * 4 atoms / molecules of SO3
Number of atoms = 2.75×10^24 atoms.

Answer 2

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!
