Answer:

Pressure of sulfur dioxide is 360mmHg

Explanation:

The total pressure of a gas mixture is defined as the sum of the pressure of each gas in the mixture.

In the mixture of the problem, there are CO, CO₂ and SO₂ as gases. Total pressure is 1465mmHg, pressure of CO is 234mmHg and pressure of CO₂ is 871mmHg, it is possible to wirte:

[tex]1465mmHg = 234mmHg + 871mmHg + P_{SO_{2}}[/tex]

[tex]P_{SO_{2}} = 360mmHg[/tex]

Thus, pressure of sulfur dioxide is 360mmHg.
