Baking: density of granulated sugar
Self-tutoring about sugar density: the tutor looks it up.
approx. 0.85g/mL = density of granulated sugar poured from the bag.
The reason granulated sugar seems less dense than water, by that figure, is that the grains have air pockets between them. If the sugar was solid crystal it would be 1.59g/mL, which is why the grains sink in water before dissolving.
