Answer:
126 mm Hg
Explanation:
the percentage by volume of oxygen in the air is 21%. Therefore it also contributes to the 21% of the total barometric pressure of the air.
Now, 21% of 600 mm Hg
=21/100*600= 126mm Hg
therefore The partial pressure of O2in Antonito’s air is approximately is 126 mm of Hg.
