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.
Hence Given mass is 8g
and molecular weight of O2 is 16×2 = 32
Hence,
Moles = 8/32 = 1/4 moles.

hey.. mate here's yur ans..
_______________________
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
