Understanding the Mole (the basics)

The Mole is an essential concept in chemistry. In this video we'll look at how to use the mole to solve chemistry problems found in general chemistry. This includes defining the mole, calculating molar mass, mole ratios, and other key concepts.

For more help with moles to grams conversions and more:

Converting between moles and grams is the cornerstone of being successful in stoichiometry, the study of chemical quantities. Take the time to learn mole conversions and you will find chemistry is much easier.

The use of conversion factors (also called factor-label method or dimensional analysis) is a more general technique for converting quantities. Once you understand how it works it can be applied to many different conversion (as long as you know the conversion factor).

Thank God for this man! My teacher doesn’t teach and I am ADHD so I have to learn in different ways. The math and science teacher, Jason, on You Tube has helped a lot. It’s just that he goes in great detail. Sometimes i need to learn a concept in a day, so I am glad I came across Wayne’s channel. Thank you sir.

Thanks a lot! I actually learned this "impossible for me thing" after 3 whole years! And the credit is all yours!!

I just learnt what School didn't teach me for like 2 years. Thank you Dr.B ! You are a gem that I found ❤️

[yasminshifa]

you don't know how much I love you <3. Learning chemistry for the first time in online school has been the WORST for me and you make it seem ten times easier than how teachers make it out to be. :)

I can believe it. After two years study Chemistry, I struggle with the concept of Moles and Avogadro's numbers. Now I understand how to do my homework I will subscribe to your channel. Thank you again

Thanks Dr.B . I am very glad to have a type of teacher like you.

Great resource when having to teach remotely, without having to generate the quality of instruction you provide.

[jasonchu]

thank you Dr. B this map is by far the easiest for me! We owe you a lot!

YEAH IT WAS IN MY BACKLOGS FOR NEET PREP THANKYOU TEACHER LOTS OF LOVE AND SUPPORT KEEP GROWING<3

[somaghosh]

These videos really help me understand better like way more better my teacher makes me understand. It is very helpful during my exams. I have science exam tomorrow and I am watching it now and it is helping me. Thank You so much Dr. B for these videos.

[mashihuzzaman]

Thank you so much for explaining this. I liked all your videos. you explain very simply

[arjelashkjau]

Thank you so much for this. It really helped!

Hi Dr B, I am struggling with 2 chemical problems. Would you mind helping me in them.
1- What mass in metal can be formed by the reaction of metal with excess Fe₂O₃, according to the thermite reaction:
Al(s) + Fe₂O₃ → Fe(s) +Al₂O₃(s).

2- Calculate the theoretical yield from the complete reaction according to the following balanced chemical equation:
Al(s) + I₂(s) → AlI₃(s)
If you are going to help me with steps please!!

number of N atoms in 0.410 mol NH3 what probably the solution to this if mol. Is already given?Thank you.

[alexandersson]

Sir please make video on electronic configuration upto Atomic number 50
Please

[bonniechang]

is there a video on molarity and practice questions :)

[ravishmirividahara]

Sir can you discuss some calculations regarding titrations

[fuzibee]

Sir you explain very nice 😊
Are you a school teacher or other else🤔

[samanthayu]

Thank you for addressing that it can be used for both micro and macro! It was the blindspot that blocked my understanding of moles.

For the answer to the question; How many molecules are there in 36.04 grams of H2O, how come is the answer 12.04 and not 1.204?
