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

[B]weight is a force measured in newtons[/B]....

[B]grams is a measurement of mass[/B]

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.

god damit, sorry im a little tired today and many things are going wrong

Edit: sorry does anybody know the atomic weight of iodine
Edit 2: its ok i have found it its 127

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.

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[sup]-3[/sup] 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 [u]is[/u] 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.

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 [b]the weight of a mass[/b].

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

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!

I guess the constant line of questioning made it out that way.

Anyway... perhaps a Header to this thread and tidy-up of nonsense/irrelevance would be a good idea?

something to effect of being Specific as you`ve pointed out in some posts here.
maybe something official? :)

[quote name='Sayo']To clarify: 1 gram of mass (which could be anything, iodine or otherwise) weighs 9.8x10-3 Newtons on the surface of the earth.[/quote]

right, as i've always been told that is true.... however, wouldnt that change with height?

e.g if you are a long way below sea level compared to on the top of mount everest, the height different is quite big and one being so much close to the center of earth and gravity, does this figure not change then????

the reason i say it might is, as we know, if you travelled (in a rocket) out of the earths atmosphere and so on then you would no long feel the earth's gravity, so distance seems to effect the force of gravity, so therefore doesnt the difference between mt everest and under sea level effect that figure?

"doesnt the difference between mt everest and under sea level effect that figure?"

Yes it does, but not very significantly.

here`s a quicky.

Gravity compression, if 2 bodies in a vacuum are atracted to each other they will gradualy move together under gravitational forces (and eventualy meet up).
this will happen at a set rate of speed, now if the 2 bodies were FORCED together faster than their natural speed under gravity alone, would this make a compression of gravity?
