In the atmosphere?

Explanation:

At sea level, since dioxygen 21% of the the atmosphere, the partial pressure of dioxygen is 0.21×1⋅atm=0.21⋅atm. What is the partial pressure of dinitrogen if dinitrogen constitutes 79% of the atmosphere?

Note that, as here and as always, the total pressure is the sum of the individual partial pressures: here 1⋅atm=(0.21+0.79)⋅atm as required.
