Suppose that in a cylinder, the oxygen has a pressure of 0.292 atm and the nitrogen has a pressure of 0.587 atm. if the total pressure inside the cylinder is 1.01 atm, what is the pressure that is due to the helium? a. 0.722 atm b. 0.879 atm c. 0.131 atm d. 1.01 atm

Hi, the posted question has some missing part. In the given question, there is no information about presence of helium gas inside cylinder. But, some amount of helium gas should be present inside cylinder.

Pressure of helium is 0.131 atm

Explanation:

For a mixture of ideal gases, we can apply dalton's law of partial pressure to determine partial pressure of a particular gas by using the following equation:

, where is total pressure of mixture and is the partial pressure of 'i'th gas.

Here

Let's assume all three gases (nitrogen, oxygen and helium) behaves ideally.

So,

So,

So,

So,

answer: you could do some invislibe ink.

explanation: i will tell you how to if u answer my question.

where's the diagram?
