ALEKS: Using mass concentration to find solute mass and solution volume

[@jah6999]

You are amazing! I passed chemistry by watching your vids consistently! Just waiting on that "Using the small x approximation to solve equilibrium problems".

[@RoxiHulet]

Ugh, that's a difficult one... It's on my list!

[@jah6999]

Ughhhh ik!! Thank you for persevering though!!🎉

Hi, I had a question about the change from mL to dL. I thought that 100mL = 1dL, so 600mL x 1dL/100mL = 6 (not 60dL)

[@shelbystucker2186]

I got the same thing.

Hey Roxi! You’re absolutely amazing thank you for all the help you’ve provided. I’m struggling with the topic “Using the maximum work theorem with chemical work.” Please helppp

[@internallyinteral]

I hate chemistry! But seeing your videos for how to solve show up when i search a question always makes me feel better 😂

[@saysayrah]

Hi Roxi :) Can you please make a video on “understanding the conceptual components of the enthalpy of solution”? Thank you !

[@kaitlynyip5911]

May you please make a video on Chem II "Deducing a rate law from the change in concentration over time" It's in Kinetics and Equilibirum. The other videos here on youtube for this are so confusing. Thank you!!

[@RoxiHulet]

I would love to make this video - I'm struggling to find a good format for it on my iPad so I probably won't get it done in time for you to use it. It is definitely a challenging problem and if you have questions, I might be able to answer them. You definitely need to use software like Excel or Google Sheets or a graphing calculator to solve the problem. I tried solving it by hand a couple times and it didn't give me an accurate-enough answer for ALEKS. Brutal problem in general...

Hi, roxi. I hope you are doing well. I’ve found your aleks videos super helpful throughout gen chem 1 and now that i’m starting gen chem 2. But, I wanted to ask if you could send me any notes over gen chem 2, we just started chapter 12. I feel like i’d learn a lot from you, I don’t have any way of contacting you then through here. So, if you are willing to help me I’d greatly appreciated. thank you so much !

I've been trying to find a way to get my notes and worksheets online so that students can view them, but I don't want to pay for a website... Do you have any suggestions on how to do it? Do you think it would work if I could somehow make them into a shareable google doc? I'm honestly open to suggestions. They're all way too big to send via email, so that isn't an option.

@@RoxiHulet Hi, good afternoon! you can make a google classroom, which is free. You can post “announcements” and in those announcements attach your notes or worksheets or even videos! All we would need would be a link and a class code to your google classroom, which you can get from the settings button in google classroom. My professor for basic chem did that for some of us gen chem 1 students to help us. Hope it helps you!!

What is ALEKS pls let me know?

[@RoxiHulet]

It is an online homework system used for chemistry and math

[@karndevvala5510]

Really good. Is it built by you?

[@karndevvala5510]

​@@RoxiHuletI am having problem learning inorganic chemistry and some in physical. Do you have any advice for me?

[@RoxiHulet]

@@karndevvala5510 For both, I just practiced over and over with many different homework problems. Repetition was the only way I was able to retain anything. They’re very difficult classes. Good luck to you! And no, I do not work for ALEKS. :)
