since all the gases are in % (100 percent) you could easily convert those percentages to grams to find the moles of O2, N2, and Ar.

Oxygen in the air is O2 like wise nitrogen is N2. mole fraction = n (mole of 1 component) / N (total mole of all components) Oxygen mole = 21 g /(32g/mol)=0.66 mole Nitrogen mole = 78 g / (28g/mol) =2.78 mole Argon mole = 1g / (40g/mol) =0.025 total mole =0.66 + 2.78 + 0.025 =...
