Given 1.115 atm of carbon monoxide reactimg with 1.553 atm of oxygen in a closed container at a constant temperatue, what is the theoretic yield of the carbon dioxide?

Answer 1

1. Write the equation and balance it.
2. I would convert CO and O2 to moles using PV = nRT
3a. Using the coefficients in the balanced equation, convert moles CO to moles CO2.
3b. Same procedure, convert moles O2 to moles CO2.
3c. It is likely you will have two different answers for 3a and 3b. obviously one of them must be wrong. The correct one is ALWAYS the smaller value.
4. Convert moles of CO2 from 3c to grams. grams = moles x molar mass. If you want it in pressure units, you can use PV = nRT.
