Title: Help on Density?
Post by: dette_xo on May 14, 2008, 01:44:12 AM: Hi there, I'm actually new here. I have a massive Chemistry EEI assignment at the moment. It consists of 6 reports on experiments we've done. So far I'm fixing up my report on Density.

And my teacher asked to include where the density of objects is important in society and where are the items of high and low density used? And I can't find anything on the internet for it.

I was also wondering what the correct density for Sugar is. Because I found one website that said 0.88g/cm3. But the teacher said that it was too low. And I suppose it is, because I've never seen sugar float on top of water :P

Any help would be greatly appreciated :)

0.88 is most likely bulk density.

(via Google)

There seem to be more densities of sucrose than you can shake a stick at

http://homepages.gac.edu/~cellab/chpts/chpt3/table3-2.html :o

What that means for you ???

Sorry, I'm not really helping here. :'(

Good luck

Clive

These are densities of sucrose solution, I believe OP asks about the solid density.

Ah .. Of course !!!
