put it inside a recipient of known volume, then wiegh the whole thing, then wiegh the empty recipient. do the substraction and then divide. takes about 5 minutes

Does it mean that you will count the density of powdered sugar just like count the density of some plant or animal in sample area 😕 Ecology is not my major, so I am afraid that you need to count one by one of those powder thingy? Oh… 🙄

denisity means mass/volume doc. no counting involved.
it’s not organism density, it’s something totally different. it’s the physical measure of density

How to measure density of sugar? Powdered,
granulated and rock candy should all have the same density since
they are made of the same substance, but I do not know how to
measure it to show that. Please help.
————————————————————————
Your best bet will be to find some liquid that does NOT dissolve
sugar, and then to add a known mass of sugar to it and see how much
volume it displaces. The tricky part with the finer forms of sugar
will be keeping entrained air form sticking to the solid. Be sure
to measure the mass of your sample and then take the ratio of
mass/volume to get the density.

First, you need to be sure that the granulated and powdered sugar do
not contain other additives such as silica or starch, which is used
to prevent caking. You can do this by dissolving each in water. If
the water remains hazy, that is a tip-off that there is some other
insoluble component present. Then, you need to weigh a sample of
each solid in a liquid in which the sugar is not soluble, for
example acetone or mineral spirits. If you carefully weigh a known
volume of the liquid without the sugar (you will know its density).
Then weigh the same known volume with part of the liquid removed so
that the volume of sugar + liquid is the same as the liquid alone,
you will know what volume of liquid has been replaced by the known
weight of dry sugar. The ratio of that weight of dry sugar alone and
in combination with the liquid is a measure of the volume of liquid displaced.
If you use a liquid whose density is already known, you save the
step of finding the density of the liquid.

Aha! I am glad to hear that! Thank you, my boy 8)

You all are discusing on the subject of 5th grade. 😆

Ok. 🙂
I m giving my own openion here,
Use Archimidi’s Principle.

Take a finely graduated measuring cylinder fill it with water upto certain mark say (50ml). Put measured quantity of dry sugar in it(say 20 gm). And find level differance in cylender.

L2 – L1 = V. 😛 Say 70-50=20ml or dm Cube

L2:final level
L1:Original level
V:Volume of sugar

then Wt/V = Density 😉 say 20gm/2ml= 1gm/ml or 1gm dm-3

Hey,
Sugar is soluble in water, you will get anmalous reults by adding it to water and seeing how much water it displaces. Do what MrMistery says, its the easiest way that will give you decent results.

ok then use saturated water for that..

True, but is still probably easier using the other method.

AGREED 😛
