A closed container is filled with oxygen. The pressure in the container is 435kPa . What is the pressure in millimeters of mercury?

(i know that 1atm=760mm Hg=101,325 Pa)

How do I use this to solve for the question? so: 435kPa*101,325=44,076,375Pa, & O2 = 32g/mol & you must have to use 760mmHg in there somehow, but then what.
The text really doesn't discuss this much, it only shows one sample prob which only gives a psi to convert to mmHg.

& how do you solve for pressure (in atmospheres) when given a msmt in "___cm's" -in a manometer- & given the atmospheric pressure in __atm?

You can use the equation:

760mm Hg=101,325 Pa

You simply write it as:

Pa = 760mm Hg/(101,325)

You then substitute this in the expression for pressure in the container:

435kPa = 435k*760mm Hg/(101,325) =

435*1000*760mm Hg/101,325 = 3362.8mm Hg

so g/mol of oxygen has nothing to do with solving??

Right. The 32 g/mol has nothing to do with it. Pressure is pressure. It would be the same for any gas. Also, I think there is a typo in the number. I think it should be 3262.8 but we are allowed only 3 significant figures.

I had picked up on that, thank you. I had that answer before but thought it was wrong.

To solve for the pressure in millimeters of mercury (mmHg) in this problem, you can use the conversion factor that 1 atm is equal to 760 mmHg.

Given:
Pressure in the container = 435 kPa

Step 1: Convert kPa to atm
To convert from kilopascal (kPa) to atm, divide the pressure in kPa by 101.325 (since 1 atm = 101.325 kPa).

435 kPa / 101.325 kPa/atm = 4.29 atm

Step 2: Convert atm to mmHg
To convert from atm to mmHg, multiply the pressure in atm by the conversion factor of 760 mmHg/1 atm.

4.29 atm * 760 mmHg/atm = 3260.4 mmHg

Therefore, the pressure in millimeters of mercury (mmHg) in the closed container filled with oxygen is approximately 3260.4 mmHg.

Now, let's address your other question about solving for pressure (in atmospheres) using a measurement in "___cm's" in a manometer, given the atmospheric pressure in ___ atm.

In a manometer, the pressure is typically measured in centimeters of a liquid, such as mercury (Hg). The pressure difference between the two arms of the manometer, known as the "manometric pressure," can be used to determine the pressure.

To solve for pressure in atmospheres (atm), you need to use the equation:

Pressure (in atm) = (Manometric pressure + Atmospheric pressure) / (760 mmHg/atm)

Here, the manometric pressure is measured in cm of Hg and the atmospheric pressure is given in atm. By substituting the appropriate values into this equation, you can calculate the pressure in atmospheres.

Remember to make sure the pressure units are consistent throughout the calculation. Convert any pressure units that are not in mmHg to mmHg before using this equation.

I hope this explanation helps! Let me know if you have any further questions.
