No of moles = given mass / molecular weight

Hence Given mass is 8g

and molecular weight of O2 is 16×2 = 32

Hence,

Moles = 8/32 = 1/4 moles.

_______________________
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
