### Finding Chemical Equilibrium Concentrations

Repost: Here is a video explaining one of Dr. Lavelle's post-assesment questions found on the Chem 14A website. I hope it's helpful!

I had originally submitted this on Sunday afternoon, but didn't receive feedback until Monday-- my file was too large. Here is a repost. Hope this is better.

### Re: Finding Chemical Equilibrium Concentrations

This is an excellent video presentation on how to find equilibrium concentrations.
The detail in going through step-by-step how to solve the math in a quadratic equation is a must view for all students that need to review how to do the math. Every step is shown in clear detail.

Introduce yourself at the end of Wednesday's class.

Why do you use moles in the ICE table if in the end your answer is in M? was that a mistake or do you not need to calculate Molarity first?

Since molarity is the moles of solute per liter of solution it does not matter if she used moles in the ICE chart as long as long as the unit of moles is consistently used and at the end the number of moles is divided by the volume to get the molarity/concentration of the solutions at equilibrium
