That first site, I tried looking at earlier and coulnd't understand where to find the information for density. The substance is a white crystaline powder that we have in class.
As far as being near gluclose that is possible, but It wouldn't help on my substance since its not close to the density.
We were giving
barium sulfate, calcium hydroxide, citric acid, fructose, monosodoium glutamate, pottassium nitrate, succrose for the options.
My density that I caculated last class was 1.345 9.981grams for a 1/2 tablespoon or 7.3934 cm3= 1.345 none of those are close to that density besides the one I had for fructose at 1.346... sure wish I could find that site again to confirm.
