Units for Concentration

Postby Grace Ramey 2K » Mon Feb 26, 2018 5:22 pm

Is it necessary, when using "Method 1" (using initial concentrations to find rates and constants), to convert all of the concentrations to mol/L instead of mmol/L? Will the final answer be different?

I don't think it matters, you should just know which ones u were working with to match the units!

Yes, I don't think it matters because you aren't using constants with fixed units and if you are consistent with what you're working with it should be fine.

Unless the problem specifies units, it doesn't matter whether you use mol/L or mmol/L because the answers will be equivalent.

Just make sure all your units match but other than that, I don't think the answer has a preferred unit.
