Just a suggestion, for the "try it yourself portion of the video, can you please work out the problem and show the steps afterward, it would really help with pinpointing mistakes if we got it wrong.

Thank you so much for helping me this saves me before my unit test ❤

[@melissaruiz2303]

Melissa, I just want to take a moment to say THANK YOU SO MUCH for being so amazing and so so helpful!! It's my first time taking chemistry since my sophomore year in high school (I'm a freshman in college now) and I've been struggling so much for the past two months. I went to tutoring, but that hardly helped and I was starting to lose all hope. But after having found you I finally realize that I AM capable of passing and UNDERSTANDING chemistry...not all hope is lost. So thanks so much once again. :) (p.s. Nice name!!)

[@soleil3847]

I am in the same boat! How did your year turn out?

[@user-ez3lv5ly5t]

I really like the way you simplify stuff and those aesthetics on the table or teaching using a bullet journal...awesome idea. love the way you communicate things.... u helped me a lot.

[@JanMarsalekWirecard]

My Exam grade is saved

[@melissamaribel]

Hooray!! 🎉

[@nicolesandrik-arzadi2596]

[@melissamaribel]

[@elenabiglan8136]

Thank you so much for all of your help! You make everything so much easier to understand! I too had been paying money for tutoring and it was not helping, but your videos make chemistry interesting again.

[@anjana7636]

OMG THANK GOD FOR U LIKE I LITERALLY LOVE U SO MUCH RIGHT NOW!! THIS IS GONNA NE ON MY FINALS AND I REALLY THOUGHT I WAS GOING TO FAIL AND U CLEARED ALL MY DOUBTS!! THANK U SO SO MUCH!!!!!

[@ziafernandez9122]

Thank you so much miss melissa! ♥️ You are a great help to our chemistry problems. I am doing my internship as a teacher in a private school here in Philippines and the assigned lesson to me is about organic chemistry, I watched your videos and I easily understood all the lessons. May God bless you 😇 Thank you so much! 💕

[@melissamaribel]

You are so welcome Zia! So happy I could help you out and if you need any more help with Organic Chemistry I have a second channel dedicated to teaching Organic Chemistry. Here's the link: kzbin.info/door/SzvQG5seY5dA59RIkZlicg

[@cengiz2645]

You’re a life saver! Thank you so much. For some reason this process isn’t even in my textbook and my teacher has never shown me this, yet I’ve been given questions on it!? If it wasn’t for you I would’ve known nothing

[@melissamaribel]

You are so welcome, glad this video helped, I'm shocked it's not in your book it's a common topic in Chemistry. Happy it makes sense now 😊

[@deantetro5650]

It really sucks, I found you the night before my final, I wish I found you sooner. But you helped a lot and I think ill pass now thank you great video

YOU ARE THE GOAT FOR REAL! I DON'T CARE IF THIS VIDEO WAS MADE FIVE YEARS AGO, THIS EXPAINS IT SO MUCH BETTER THAN MY CHEM TEACHER ITS CRAZY. never get taught chemistry by a fifty year old named Alfred who doesn't allow any devices or drinks in the class, you are sure to fail.

[@yousefahmed8528]

Can you give me you name in instgram pleasw

[@mustaphahall7595]

Melissa, I just calculate (162.1g) X (.74) which gives me the g and then divide that by the Mass which leads me to the answer without having to use the empirical formula. A quick way I was taught back in Germany.

Our teacher includes your videos with the lessons, and I'm surprised by how much I'm actually understanding compared to when I first did chem 1 in highschool. Thank you so much!

[@MythosandMeadowASMR]

Hi Melissa! Not sure if you'll see this comment but I'll ask anyway. I was given the question: "Complete combustion of a 0.0100 mol sample of a hydrocarbon, CxHy, gives 1.792 L of CO2 at STP and 1.261 g of H2O. (a) What is the molecular formula of the hydrocarbon? (b) What is the empirical formula of the hydrocarbon?" There is no molar mass given. How do I solve this?

[@pafiffikus4382]

you did a better job at explaining how to do this than my teacher did

[@melissamaribel]

Thank you!

[@STP31]

Thank you soo much Love from Malaysia

[@akashayaqub7175]

Your videos make a lot of sense! I just had one question...is the table necessary to draw out every time you convert grams to moles? (I just learned that with Avogadro's number). The way my teacher taught it was to just divide by the mass and then to divide again by the smallest number for the empirical formula part. I really appreciate the time and effort you put into these videos!

[@jayam812]

She does mention it in the beginning and the middle of the video, she says it's the Molecular Molar mass and it will always be given because it's the only way to find the Molecular formula. I had the same question until I went back to watch/listen more carefully haha. Cheers 😛
