39. Three of the primary components of air are carbon dioxide, nitrogen, and oxygen. In a sample containing a mixture of only these gases at exactly one atmosphere pressure, the partial pressures of carbon dioxide and nitrogen are given as P co2 = 0.285 torr and P n2 = 593.525 torr. What is the partial pressure of oxygen?

They stated the total pressure was 1 atm which is defined as 760 torr so all you need to do is subtract the partial pressures that are NOT oxygen from 760.
760 - (593.525 + 0.285) = 166.19 torr for the O2

Im not the smartest person but i think u take each torr value and divide by 760 to change it to atm
.285/760=.000375atm
593.525/760=.781328947 atm
then add these and subtract from 1
answer=0.218671053atm x 760 to convert back into torr = 166.19 torr oxygen

YOU: I as quickly as heard "genius is one p.c. notion and ninety p.c. perspiration". What approximately the different 9% jeenyus? Oh yeah, and the era is meant to be interior the charges ("'...perspiration'.") loser.
