partial of oxygen pressure =452mmHg

total of oxygen pressure =780mmhHg

mole fraction = partial pressure/total pressure

452/780= 0.579

mole fraction of oxygen=partial pressure of oxygen/total pressure.i.e mole fraction of oxygen=452/780=0.579

The partial pressure of oxygen is 452 divided by the total pressure which is
780 that is 452/780=0.579.Answer
