Discussion Overview

The discussion centers around the concept of "g atoms" in relation to a single atom of an element, exploring its significance and implications. Participants engage with the definitions and meanings of gram-atoms, moles, and their relevance in chemistry, while also addressing the nature of the question posed.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant questions the meaning of "number of g atoms in one atom of an element," suggesting it may imply a direct relationship to grams of that element.
  • Another participant introduces the concept of a mole, explaining it as a quantity similar to a dozen, specifically referencing Avogadro's number.
  • A participant emphasizes the importance of understanding the information provided rather than seeking direct answers, advocating for problem-solving skills.
  • One participant expresses skepticism about deriving the number of g atoms from first principles, noting the historical context of its experimental determination.
  • Another participant suggests that, despite the complexity, it is possible to evaluate the plausibility of the provided numerical options based on the understanding of g atoms.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the significance of the number of g atoms in one atom of an element, with various interpretations and approaches presented. The discussion remains unresolved regarding the clarity and implications of the original question.

Contextual Notes

The discussion highlights limitations in understanding the term "g atoms" and its application, as well as the dependence on definitions and the historical context of the concept.

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.
