Thank you for sharing this problem with all us. I have two comments : 1. Under the list of compounds Sodium shows a valence/charge of +2 instead of (Na+); and 2. You mentioned molecular weight instead of molarity under 12:17 - 12:33 minutes on the video. The units are correct for molarity (mol/L). Overall great video! Thanks
Haha, I love how you get into the details. A true engineer indeed. Thanks Geder, I honestly did not realize those errors, thank you for pointing them out :).
Hi great video, thanks for sharing. One comment, regarding molecular weight formula, I guess it should be Alkalinity concentration/molecular weight. Thank you.
Thank you @directhub. For example if the CO3 2- ion was also present in the list above , how would it be solved? Would it include adding the normality for HCO3 - and CO3 2- together
I see that on the topics that this could be on the exam but would a question like this even pop up since it isn't even in the manual. That's really frustrating
Hi Blakely, I completely understand how frustrating it can be especially for these chemistry questions. This stuff is not in the FE Handbook but knowing how to balance chemical equations and conducting a stoichiometric analysis is a topic I would focus on before taking the FE. For the civils, this is especially important when examining the lime softening process (e.g. using lime softening equations on page. 341 in FE Handbook 10.0.1.) If you are taking the Environmental FE I would definitely make sure you understand how normality is related to the concentration of a chemical - AND how to normality units when conducting a stoichiometric analysis. For the chemistry section on the FE, the primary learning goal is to know how to 1) balance equations 2) relate chemicals by their mol to mol and weight ratios and 3) solve for whatever the problem asks. For the civil FE, I believe knowing how to conduct a stoichiometric analysis is also a topic you should prepare for. I hope this helps!
@@directhubfeexam Thank you for the swift reply my brother, greatly appreciated. These videos you do are amazing as well, keep doing what you're doing.
Thank you for the all videos. I've watched most of your videos and here is a point: you repeat some simple points during solving problems many many times and its going to be really boring and waste the time.
You're welcome. Some like this style while others don't. I try to not repeat myself too often but it is what it is. Thank you for watching the videos! I hope they're helping with your prep.

Direct Hub no problem.
Hi great video, thanks for sharing. One comment, regarding molecular weight formula, I guess it should be Alkalinity concentration/molecular weight. Thank you.
thank you, but i don't understand how you changed the position of 61.019 and it was flipped?
Thank you @directhub. For example if the CO3 2- ion was also present in the list above , how would it be solved? Would it include adding the normality for HCO3 - and CO3 2- together
Yes! That's exactly what I would do. Since HCO3- + CO3 2- is the total alkalinity. Then the sum of those two would be the total alkalinity.

MW in Reference Manual
where do you find this in the FE manual?
eng.mohammad ja'afreh I don’t think it’s in there.

@@directhubfeexam I see and thank you so much
