Consider this molecular-level representation of a gas.
If the partial pressure of the diatomic gas is 0.480 atm, what is the total pressure?

Answer:

partial pressure of one species = molar fraction of that species x total pressure

so…
P diatomic = mole fraction diatomic x total pressure

rearranging
Ptotal = (0.480atm) / (3 / 14) = 2.24atm
