Question

a gas mixture is exerting a pressure of 1.04 atm inside a sealed container. The gas was found to be a mixture of carbon dioxide and nitrogen gas. If the mixture is 42% CO2, what is the partial pressure of nitrogen

Answer 1

Partial pressure of Nitrogen = 0.6032 atm

Step-by-step explanation:

According to Dalton's law of partial pressure, at constant temperature, the total pressure exerted by a mixture of gases that do not react with one another is a sum of the partial pressures of the individual gases. And the partial pressure of each gas is proportional to their percentage composition. The partial pressure of each as is given as

Partial Pressure = (Percentage composition) × (Total pressure)

In this question, a gas mixture of Carbon dioxide and Nitrogen exerts a total pressure of 1.04 atm

The mixture contains 42% CO₂, meaning it contains 100-42 = 58% of Nitrogen.

Partial Pressure of Nitrogen = 0.58 × 1.04 = 0.6032 atm

Hope this Helps!!!
