Question

A mixture of gases has a total pressure of 1465 mm Hg. The mixture is made up of carbon monoxide, carbon dioxide and sulfur dioxide. What is the pressure of the sulfur dioxide gas, if PCO = 234 mm Hg and PCO2 = 871 mm Hg?

Answer 1

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:

$1465mmHg = 234mmHg + 871mmHg + P_{SO_{2}}$

$P_{SO_{2}} = 360mmHg$

Thus, pressure of sulfur dioxide is 360mmHg.
