It depends upon the temperature.

PV=nRT, that sort of thing?

Thank you. Can you pl. furnish me the density of Oxygen at 25 Degree Celsius and Pressures 14 kg/sq.cm and as well as at 204 kg/sq.cm?

Thanking you in Advance.

Ahem, you've been given an equation that contains the volume of the vessel (V) and the number of molecules (n) in moles. You should from this equation be able to do your own homework and get an answer.

does no one know what books are anymore.

or how how to use reference material or at least find, that they have to be told the answer.......... period.

^{tongue in cheek thinking.....}

I wonder if one would start a web site, that has engineering members.... like CR4.

that provided answers and the work with it, for a fee.

But these answer would have some type of copyright, that if used for home work, it has to labeled where the actually answer and the work were being used and be stated when the question was being answered.

No, if you were going to make money, you couldn't do the last part, plus the quality of the future of engineers would diminish more than it is now for fill the 'Push Button for Answer Generation'

Actually its Push Button for_______ ^{and fill in the blank such as: entertainment, answer, service, ect.....} Generation

You've got your T and you've got your P.

V is the volume of your container, and n is the number of moles of oxygen.

R is the gas constant. The wiki link has a great number of conversions to the more popularly used units of measurement. Just make sure your units cancel out properly and you should be given your answer.

I'm not sure how much it matters in industry due to my limited experience, but it should be noted that the ideal gas law gives values for, well, ideal gases. I'd suggest looking into an equation that works for real gases such as Van der Waals. Again, I'm not a professional in the field, so the ideal gas law may be suitable for whatever you're doing.

A mole of gas occupies 22.4 litres at STP. PV=nRT gives the volume at different numbers of moles, pressures and temperatures. So what's the problem?

Also, it seems that you've already asked this question once before, and received a slew of pretty decent answers.

You lead them to water, hose them down, float them onto a raft into the middle of the lake and they still don't drink while complaining of thirst. Is it now cruel or kind to drown them?

There are a number of Sethuraman R. on Linkedin.

Some claim to be consultants. Are you one of them?????????
