Unless I'm misunderstanding your question, I would assume one gram of anything weighs one gram... :confused:

weight is a force measured in newtons....

grams is a measurement of mass

theya are different things which are for some stupid reason used totaly incorrectly in the "real world"... (as in NOT scientific world)

and no i dont know its weight.

does anybody know the weight of iodine per gram

On Earth, it's 9.8x10-3N.

[i]"you`re perfectly correct! :)" -- YT2095

that is physically impossible as weight is measured in newtons!

Weight (Newtons): the vertical force exerted by a mass as a result of gravity
Mass (grams): the property of a body that causes it to have weight in a gravitational field

and is perfectly useless in Chemistry!

a Gram is just that, as is a Mol.

Physics need not apply or try to over complicate matters needlessly!

a gram is a gram in Chem, nowt more or less.

yeah sure, not saying thats wrong!... im saying that a gram is a gram and a gram is a measurement of mass, not of weight!

This is neither a chemistry thread nor a physics thread, so the context is lost.

5614 is simply responding to the question that was asked, as have I.

does anybody know the weight of iodine per gram


was the question that was asked, and the answer is 1 Gram.

or do we talk about Newtons and light speed and radioactive decay as well?

No, the gram is a unit of mass.

Weight is a force: mass x acceleration.


[edit]

To clarify: 1 gram of mass (which could be anything, iodine or otherwise) weighs 9.8x10-3 Newtons on the surface of the earth.


Even if that isn't the answer to the question that he really wanted to ask.

but in Chem, non of that applies (outside a centrifuge or chromatographs etc...)

and his question was Chem based, In fact it was a follow on from his other question in the nitrogen triiodide thread posted a little while earlier :)

Exactly which part of the question would you say makes it a chemistry question?

If you take the fact that it contains the name of an element, then by your reasoning if we swap the word 'iodine' for the word 'koala' then it becomes a zoology question, despite the fact that it is still calling for a mass->weight conversion, which is a physical function.

Despite the trite but popular phrase, there is such a thing as the wrong question.

I suggest in future we ask for clarification on ambiguous questions (even where we don't really need it), since this thread is going to be highly googled and we'd probably rather not get a reputation as a science site where the questions and answers fail to match up yet draw no comments.

you asked: "Exactly which part of the question would you say makes it a chemistry question?"

how much Ammonium Tri Iodide would you get from 100g would it still be 100g


taken from here: http://www.sciencefo...wreply&p=110899

that`s what makes me think it`s chem rellated only :)

Another post in another thread isn't really what I'd call "a part of the question".

Regardless, he asked for the weight of a mass.

perhaps it would be prudent to ask HIM what he meant instead?

we can bash this around all day and still be non the wiser :)

I know what he meant, but that doesn't mean I'm going to splurge an answer to a question he didn't ask in this thread.

Reason:

, since this thread is going to be highly googled and we'd probably rather not get a reputation as a science site where the questions and answers fail to match up yet draw no comments.

fair enough, but being too the point and addressing the question as I knew it by reading his previous, demonstrates understanding on my part and misunderstanding with the rest.
I`m not to blame here!
