How do you determine the inital concentration for SO2, given the moles of SO3?

[Brianna Cronyn Lec3E]

Hi Gabi,

Let me run you through how I found the final concentration for SO2 given the moles of SO3. Initially, it is at 0 as there is only SO3 added.

So, I first took the moles of SO3 and turned that into concentration (mol/L) by dividing the moles given by the liters given of the container.

Then, I created an ice table with that as the initial concentration for SO3. I resulted in seeing that for O2 it is +X and for SO2 it is +2x.

This means essentially that the concentration for SO2 is double that of O2. We are given moles of O2, so I took that and divided it by liters to get the concentration fo O2 and doubled that to get the concentration of SO2.

Hope this helps!
