💁‍♀️ HI I'M MELISSA MARIBEL
I help students pass Chemistry and Organic Chemistry. I used to struggle with this subject, so when I finally graduated with a bachelor's degree in Chemistry, I became a tutor so that you wouldn't have to struggle like I did. I know that with the right help, YOU CAN LEARN ANYTHING!

This actually helped me well you did and I thank you so much for this. Our chemistry teacher is good but in my opinion what makes it fun to learn more about anything is your sense of humor, basically learn to have fun with the subject and students. And you are like that so that’s pretty great I subscribed to your channel cause I found it very helpful and you actually have explain very well. We have a EOC test tomorrow 😰I don’t expect to get a 90% if so then that’d be a miracle but anyways I don’t mind getting a good grade and or above approaches I just want to pass. Once again I thank you for creating this, and I am now considering myself to be one of your new students here 😁. Be safe and God bless!

Please let me know if you already have videos and notes somewhere for those or if you have plans in the near future to put that stuff out.

I guess you put 1 mole when you are computing the molar mass because it's the atomic weight that's important there but you put the coefficient of the balanced equation when you calculate the mole to mole ratio.
