Calculating Concentration of CO in a Mixture

In summary, the conversation discusses two cylinders, one containing pure CO gas and the other containing zero air. The question poses the concentration of CO in the mixture and how to calculate it, as well as the total gas volume after one minute and how to convert CO volume to weight. The concept of "zero air" is also explained. Ultimately, it is concluded that there is no significant reaction between CO and O2 without a catalyst.

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?

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??

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?
 
  • #7
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 !
 

1. How do you calculate the concentration of CO in a mixture?

To calculate the concentration of CO in a mixture, you will need to know the volume of the mixture, the volume of CO in the mixture, and the total moles of all gases in the mixture. The equation for calculating concentration is: CO concentration (mol/L) = (volume of CO (L) / total volume of mixture (L)) x (total moles of all gases in mixture (mol)).

2. What units are used to measure the concentration of CO in a mixture?

The concentration of CO in a mixture is typically measured in moles per liter (mol/L) or parts per million (ppm).

3. How do you convert ppm to mol/L?

To convert from ppm to mol/L, you will need to know the molecular weight of CO and the density of the mixture. The equation for converting ppm to mol/L is: CO concentration (mol/L) = (ppm x density of mixture (g/L)) / molecular weight of CO (g/mol).

4. Can the concentration of CO in a mixture be higher than 100%?

No, the concentration of CO in a mixture cannot be higher than 100%. This is because the concentration is a ratio of the volume of CO in the mixture to the total volume of the mixture, and the maximum volume of CO in a mixture is equal to the total volume of the mixture.

5. Why is it important to calculate the concentration of CO in a mixture?

Calculating the concentration of CO in a mixture is important for several reasons. It allows us to determine the amount of CO present in a given volume of the mixture, which is important for safety and environmental considerations. Additionally, it helps in determining the efficiency of processes that produce or remove CO, and can aid in troubleshooting any issues that may arise.
