What is the partial pressure of carbon monoxide gas in a sealed vessel that has a total pressure of 2.68 atm and partial pressures of 1.56 atm for oxygen and 0.65 atm for carbon dioxide?

Partial pressure of CO in the sealed vessel is 0.47 atm.

Explanation: From Dalton's law of partial pressures, "Total pressure is the sum of partial pressures of the gases present in the mixture."

So, total pressure = partial pressure of carbon monoxide + partial pressure of oxygen + partial pressure of carbon dioxide

Let's plug in the values in the formula:

2.68 atm = partial pressure of CO + 1.56 atm + 0.65 atm

2.68 atm = partial pressure of CO + 2.21 atm

partial pressure of CO = 2.68 atm - 2.21 atm

partial pressure of CO = 0.47 atm

Hence, the partial pressure of carbon monoxide gas in a sealed vessel is 0.47 atm.
