Air contains 78.08% nitrogen, 20.095% oxygen, and 0.93% argon. calculate the partial pressure of oxygen if the total pressure of the air sample is 1.7 atm. a.

partial pressure in a mixture of two or more gases will be given by formula

= mole fraction of gas * total pressure

now here mole fraction is same as percentage of gas in the mixture

Now mole fraction of oxygen is 0.20095 (20.095%)

now here pressure of oxygen in the mixture is given as

so pressure due to oxygen in the mixture will be 0.342 atm

ok

the components of a vector are the parts of the vectors that are to each other.
