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.

Answer:
45.8 mmhg
Explanation:
According to Dalton's law of partial pressure, the total pressure of a gas mixture is the sum of the partial pressure of the individual gases that make up the mixture.
Mathematically, the law can be expressed as:
[tex]P_{total} = P_1 + P_2 + ........ + P_n[/tex]
In this case,
[tex]P_{total}[/tex] = 632.0 mmhg,
[tex]P_{co2}[/tex] = 124.3 mmhg
[tex]P_{N2}[/tex] = 461.9
[tex]P_{O2}[/tex] = ?
[tex]P_{total} = P_{co2} + P_{N2} + P_{O2}[/tex]
632.0 = 124.3 + 461.9 + [tex]P_{O2}[/tex]
[tex]P_{O2}[/tex] = 632.0  + 124.3 + 461.9
= 45.8 mmhg
The partial pressure of O2 is 45.8 mmhg
