Helium is mixed with oxygen gas for deep sea divers. calculate the percent by volume of oxygen gas in the mixture if the differ has to submerge

i think its 5049.

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
