AI Thread Summary
To find the isotopic mass, mass spectrometry is the most effective method, as it allows for precise measurement of the mass of individual isotopes. If a sample contains a single, isolated isotope, other accurate methods for determining molar mass can also be used. Understanding the concept of isotopic mass involves recognizing that it refers to the mass of a specific atom of a particular isotope. Examples and further clarification may be beneficial for those preparing for tests on this topic.

How to find the isotopic mass ??

Hello everyone!

I have a test in 2 days, and I was trying to understand how to get the isotopic mass but I really couldn't. it's confusing. can anyone help me? and if there are some examples I would be thankful.

Thanks,

You mean mass of an atom of specific isotope?

Mass spectrometry sounds like the most obvious choice. But if you have a sample containing just a single, isolated isotope, any precise method of determining molar mass will do.
 
It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
