    moles?? ever heard of them? --- n = 0.686/32.0

     Temp = 278K //// P = 849mmHg /// R = 62.4

       PV = nRT

       V = (0.686/32.0)(62.4)(278)/849

       V = 0.438022 L or 438.022 mL <<< round for sig figs

    Convert mass of O2 into moles

    Convert temperature to Kelvin

    Convert pressure to atm

    Plug into ideal gas law and calculate V. Convert V from L to mL
