asked • 01/30/18At STP, air can be considered to be a mixture of ideal gases: 21.1% O<sub>2</sub>, 78.0% N<sub>2</sub> and 1.00% Ar by volume.

a) Calculate the partial pressure of each gas at STP.

This is what I've come up with:

X_{N2}= 21.1/100 = 0.211 x 1atm = 0.211 atm

This is what I've come up with:

X

X_{O2}= 78.0/100 = 0.780 x 1atm = .780 atm

X_{Ar}= 1.00/100 = 0.0100 x 1atm = 0.0100 atm

b) calculate the density of air in g/L at STP.
