Question

find the gram molar volume present in 3 moles of oxygen.​

Answer 1

One mole of oxygen atoms has a mass of 16g. So three moles of oxygen atoms would have a mass of 48g.

However, you would never get moles of oxygen “atoms”, as oxygen always pairs up into molecules of O2. And one mole of oxygen molecules has a mass of 32g, so three moles would have a mass of 96g.

Oxygen atoms occur naturally, but only temporarily, as they are highly reactive. So you wouldn’t naturally get a mole of oxygen atoms.
