unit of concentration

Postby Hyein Cha 2I » Wed Mar 07, 2018 8:16 pm

A lot of the hw questions give concentration in mmol/L instead of mol/L. Must we always convert fo mol/L or can we leave it as mmol/L ?

I think it depends on the question. If its asking for units of K you could probably use mmol. Same with if its asking which order reaction it is. The question will probably specify-- I don't think you'll get points taken off if you use mmol vs mol.

unless the question specifically asks for you to convert the units, then you should be fine just solving in whatever units are given

I believe you must only convert mmol to mol or vice versa if the question explicitly states to do so.

I think the important thing to remember is to make sure that all your units match.
