It was found that in a diving gas mixture for a certain altitude, the total predicted pressure is "8.38 atm". If the partial pressure of oxygen gas must be "0.21 atm" underwater, what must the mol fraction be of oxygen gas?

This is asking you to use assume
P_(O_2) = chi_(O_2(g))P_(t ot) where
chi_(O_2(g)) is the mol fraction of"O"_2 in the diving gas mixture andP_(O_2) is its partial pressure in the diving gas mixture.
Since we want
"0.21 atm" = chi_(O_2(g))("8.38 atm")
=> color(blue)(chi_(O_2(g)) = 0.025)
or
