Just confirming, when calculating for K or Q, the concentrations will have to be converted into moles/liter if the concentrations given are in mmol correct?

To avoid calculation errors, yes, it is best to convert to mols. If you don't you need to be careful with your units throughout the entire problem. Since Molarity is in Mol/L, it is easiest to convert to mols.

It's okay to make the ICE table with just mol (as opposed to mol/L) and then divide it by volume later. But, to be safe, yes, it is better to convert them all beforehand. So, for mmol, you would just multiply 10^-3 and divide by the volume
