AI Thread Summary
The discussion centers on understanding the concept of "g atoms" in relation to elements and moles. A mole, defined as approximately 6.022 x 10^23 entities, is compared to a dozen, emphasizing its role as a unit of measurement in chemistry. The term "gram-atom" refers to a quantity of a substance containing Avogadro's number of atoms. The conversation highlights that while the exact number of g atoms in one atom of an element is complex, participants are encouraged to use their knowledge of g atoms to deduce plausible answers from the options provided. The importance of critical thinking and problem-solving in chemistry is emphasized, rather than seeking direct answers.

Number of g atoms in one atom of an element are?

1.66*10^-24
10^-23
10^-22
10^-28

What does number of g atoms in real means?
Does it mean 1g of atom in one atoms of that particular element?

hi xiphoid! welcome to pf! :smile:

a mole is a number of things, like a dozen​

… to be precise (almost), 6.022142 1023 things :wink:

if you go into the garden and find 602,214,200,000,000,000,000,000 moles, that's a mole of moles! :biggrin:


from http://en.wikipedia.org/wiki/Mole_(unit ) …

The name gram-molecule was formerly used for essentially the same concept [mole]. The name gram-atom (abbreviated gat.) has been used for a related but distinct concept, namely a quantity of a substance that contains Avogadro's number of atoms, whether isolated or combined in molecules.

Thus, for example, 1 mole of MgB2 is 1 gram-molecule of MgB2 but 3 gram-atoms of MgB2

So what do you think should be the answer to my question?

It is not about what Tiny Tim thinks, it is about what you can do with the information given. It is up to you to solve the problem, we can only give you hints.
 
I know this and that is the reason for me to come here, so taht I cannot get the direct answers but get the hint to solve my doubt and use my brain in the process too...

Nobody, as far as I can see, could work out from first principles what the "Number of g atoms in one atom of an element are". (It needed waiting nearly a century before it could be found experimentally.)

However you are not quite asked to, and it is possible for anyone who only knows what a g atom is, means, and not any other information, to give reasons why one of those answers is far more plausible than the others.
 
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...
