Moles of oxygen = mass/molar mass of O2 = 8/31.998 = 0.25 moles.
Number of particles = moles x 6.02 x 10^23 = 0.25 x 6.02 x 10^23 = 1.505 x 10^23 particles.
Hope this helps!
Hola!
We know,
1 Mole of anything has 6.02 ×

particles
According to Question,
6.02 ×

= 1 Mole
Thus,
1.8 ×

/ 6.02 ×

= 0.33 Moles
hope it helps!
