If a mole were to contain `1 xx 10^24` particles, what would be the mass of - (i) one mole of oxygen, and (ii) a single oxygen molecule?

Text Solution

Verified by Experts

Mass of 1 mole of `O_(2)` is its molecular weight in g, i.e. 32 g
`therefore` mass of a single `O_(2)` molecule `=("mass of 1 mole")/("no. Of molecules in 1 mole")`
`=32/(1 xx 10^(24)) = 3.2 xx 10^(-23)` g
