Calculating the abundance of isotopes using mass spectra 

When u thought u were signing up for chemistry but it turned out to be maths

I like how you go over the basics as some people might lose focus in between and say "how did that happen?"

Thank you, you made this look so easy!!

what would you do if the element had more than 2 peaks, or would they not ask such a question? great video btw thanks

What do you do if you have more than 2 isotopes in terms of x?

I have to say again, the chemistry legend .

thank you very much for all the help I got from you. :D

Would they give you more than 2 isotopes for working out the abundance? If so what changes would you make ?

thank you so so so much. this has been losing me marks in every paper :L

Can you make a video on how to find the species of organic compounds when m/e and relative height is given on table?

Sir How do we know which one is 25 and which one is 75 ? If we multiply 115 with x so its abudance would be 25.

Thank you so much Sir! :)

Sir what to do if there are more than 2 elements

thank you very much sir

If there are more than 2 peaks?

Using your videos for my IAL tomorrow! ^.^

I am having trouble answering past year papers and textbook questions, please make videos on those too!

but how do you get the relative atomic mass? looked at the video for "calculating relative atomic mass from mass spectra" - the work that I have been given does not give an numerical number for abundance nor a percentage - instead the peaks have the labels of the M/Z - and the Y axis - abundance goes up to 1,000,000 with that limited information I am suppose to figure out the TIC, the M/Zs, and then the percent abundance if someone can get back to me on this super fast that would be fantastic - but im not going to hold my breathe on that thank you though, in the class this is for - the professor hasn't taught shit as far as calculating any of this, and after hours of searching for a calculation (which is absurd) I found this video - which has been extremely helpful - but without the correct relative atomic mass, the calculation means nothing

pleaseplease please please please please please please please please please please please please please please please please please please please please do more past papers

Your should change your intro man.... It's so annoying
