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.
 
I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...
I'm trying to find a cheap DIY method to etch holes of various shapes through 0.3mm Aluminium sheet using 5-10% Sodium Hydroxide. The idea is to apply a resist to the Aluminium then selectively ablate it off using a diode laser cutter and then dissolve away the Aluminium using Sodium Hydroxide. By cheap I mean resists costing say £20 in small quantities. The Internet has suggested various resists to try including... Enamel paint (only survived seconds in the NaOH!) Acrylic paint (only...
