A new planet is found! Calculate the mole fraction of oxygen at 1000 m for this promising

planet, with a gravity constant of 8 m/s², an atmospheric temperature of 300 K, 10% oxygen

(MW: 36 g/mol) and 90% Ne (21 g/mol) at the ground level. Hint: the barometric formula is

[P= Poe ^-Mgh/RT

Express your answer in terms of Euler's number e.
