According to Dalton's Law of Partial pressures, the sum of the partial pressures of the individuals gas molecules that occupy a specific volume allows us to find the total pressure or find one of the partial pressures if the total pressure is known.

Partial pressure O2 = 632 - 124.3 - 461.9 = 45.8 mm Hg.
