8g of ozone would contain 3.0115*10^23atoms of oxygen. So one mole of Oxygen atoms has a mass 16 grams. So number of atoms of oxygen in 8 grams of ozone will be exactly half of Avogadro number i.e.3.011×10^23.

no. of moles of O =12/16=3/4moles
no. of atoms in one mole=6.022×10^23atoms
no. of atoms in 3/4moles are=3/4(6.022×10^23atoms )
=4.5165×10^23atoms (approximately )
