Calculate the mass percentage of oxygen in dry air?

SOMEONE ASKED πŸ‘‡

Calculate the mass percentage of oxygen in dry air?

HERE THE ANSWERS πŸ‘‡

  • 23.1%

    add up the first few (Mole fraction x Molar Mass), you’ll see the molar mass of dry air is ~29

    divide oxygen’s (Mole fraction x Molar Mass) / 29 and you’ll get .231135…

    so, to 3 sig figs: oxygen is 23.1% by mass in dry air
