molar mass of oxygen gas = 32g
no. of moles in 8g = 8/32 = 0.25 moles
no. of particles(molecules) = 0.25 * 6.02 * 10^23 = 1.5 * 10^23
no. of moles in 8g = 8/32 = 0.25 moles
no. of particles(molecules) = 0.25 * 6.02 * 10^23 = 1.5 * 10^23

Hi ☺️☺️
_______________________
Molar mass of oxygen = 32 g.
So
32 g of oxygen = 1 mole.
1 g of oxygen = 1 / 32 mole
8 g of oxygen = 1 / 32 × 8
⇒ 1/ 4 moles
No of particles = 1 / 4 × 6.02 × 10²³
⇒ 1.5 × 10²³
