Question

The partial pressure of oxygen at 1atm is ________________

(a) 0.2000 atm

(b) 0.2098 atm

(c) 0.2099 atm

(d) 0.2096 atm

I have been asked this question in a national level competition.

This is a very interesting question from Estimating Oxygen Solubility in section Mass Transfer of Bioprocess Engineering

Answer 1

The correct answer is (c) 0.2099 atm

For explanation: The mole fraction of oxygen in air is 0.2099, so the partial pressure of oxygen at 1 atm air pressure is 0.2099 atm.
