Question for Madscientist

raistlin - 14-7-2002 at 18:09

Hey man, do you remember those books I told you about? Well I was wondering if I need to get really good at what was in the one before moving on to the Langes one. I just want to know if I should just read it then go on to the next book or if I should get really good with the one then move on....

Lange's is a reference book, not a textbook. You won't read straight through it (unless you are remarkably bereft of other amusements). Madscientist won't be answering any questions for a while because he's gone on a trip for a week. I'll be gone for more than a week myself starting this coming Friday, so hopefully he'll be back by then.

Hehe, I forgot about that trip of his...

I had forgotten he had mentioned he would be gone for a while... You think he will be back this Friday? Well anyway, I know that Lange's is only a reference book, but what I had meant is, do I really need to understand things such as what a mole is before I move on to it, or do I just need to get a basic idea of what chemistry is?

A mole is the SI unit for amount of substance. The quantity of a substance that contains as many molecules or formula units as there are atoms in exactly 12 g of carbon-12. Thus, one mole of oxygen [0]= 16g. One mole of Chlorine [Cl] = 35.45g, etc.

Umm, Psycho, Im not meaning to be rude, but what does moles and molar ratios have to do with my original post?

Im really not trying to be rude, so please dont take it that way...

Ummm. Nothing really, I think you mentioned it somewhere in this thread... somewhere, maybe. Oops. Disregard my posts

Lol, its ok Psyhco. Im pretty sure someone out here was benifit by that info. You should consider making a post with the moles for all of the elements. (I wouldnt do them all, just some though...)
