Calculating atomic weight | Chemistry | Khan Academy

Calculating atomic weight.

Chemistry on Khan Academy: Did you know that everything is made out of chemicals? Chemistry is the study of matter: its composition, properties, and reactivity. This material roughly covers a first-year high school or college course, and a good understanding of algebra is helpful.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

For free. For everyone. Forever. #YouCanLearnAnything

When you regret talking while the teacher is teaching








But you remember you have Khan Academy

[parallelparkdaudette]

Thank you brother I'm preparing to study in nuclear engineering from the ground up and these PDF textbooks aren't explaining nearly as well as you do. Thanks!

[Zaillith]

Straightforward and easy to understand video. Very good thank you!

[ananyarani]

You teach very
Will you guys please post a regular videos on chemistry with full concept and question solving
Please 🙏🙏🙏

[HabibaMohamed-fhbm]

Thank you soo much !!
I really needed this.

Wouldn't the atomic mass of carbon 13 be 13 since 13 is the sum of all the protons and neutrons in the atom?

[vaibhavmadan]

What is the difference b/w atomic mass and relative atomic mass?

[zwnderella]

thank you so much for the simple explanation ! ahh i'm happy i found this channel

What is the atomic mass of boron from the atomic boiling point of carbon?

[diegorojas]

I have one question, I'd appreciate you can help me. Is the abundance always the same?? In every sample of carbon involved in an experiment, the abundance percentage is the same? Thanks in advance.

[bruhduh]

I did not understand a thing you said :(( I'm going to fail Science!! Why is it so hard :(

[shirtposting]

how does the rarity of the 2 substances decide the weight of it? Please someone answer this for me, i'm so confused.

[ryanleeharrell]

I dont understand. Where did the the numbers that you multiplied and added together come from?

[mbenitez]

how do I know how many isotopes an element has, for example there is carbon 12 and carbon 13, is there such thing as carbon 14 or carbon 11?

I know hydrogen has 3 of them
why

[tusharvaswani]

but how you get the atomic mass of C-12 and C-13

[daquay]

Hi, can you tell me which apps do you use to make lessons?Thanks for your videos, they are really helpful.

[vaibhavmadan]

Sir Carbon has one more isotope - the one having 6 protons and 8 neutrons. Why you did'nt include that while calculation Average atomic mass?

[sercia]

How cqn u calculate that 13^C is 13. 0034 amu?

[dilnasssssss]

I am a bit confused cause the number under the name of the element is an atomic mass according to the periodic table. Why do you call it atomic weight? I'll search for the answer and watch the next videos(maybe I'll get an answer there) but if someone can help me I would really appreciate it.
