Calculating Concentration of CO in a Mixture

[nigi81]

CO oxidation ??

There are two cylinders. First is a CO cylinder having pure 99.97 CO gas
and second having zero air.

CO is given at 0.1LPM rate and air at 0.9LPM. what is the concentration of CO and what percentage in this mixture?? How to figure it out?

 

[chemisttree]

Concentration in what units? Moles per liter? The concentration expressed as percentage can be in units of percent by weight or percent by volume. Which will you choose to use?

How much total gas will there be after one minute? What volume of CO will be in this amount? How might you convert this volume (assuming standard pressure and temperature) to weight?

What does "zero air" mean??

What does "zero air" mean??

Zero air is dry, compressed air that has no hydrocarbons in it. The hydrocarbons can come from the compressor's oil used to fill the cyls.

Ya learn something everyday!

Back to the original question - does CO and O2 react at room temperature/pressure?

 

[chemisttree]

No significant reaction without a catalyst.

No significant reaction without a catalyst.

That's what I thought, so the original question is just asking you at add 0.9 and 0.1 !
