How do you find the volume of a rock sugar? - Answers

I suppose the question is what your plans are for the rock sugar.If you know the density, then you can estimate the volume by using the weight.You can drop it in a liquid with a measured amount of volume, and check for volume changes. The problem is that the most common liquid one might use is water which will also slowly dissolve the sugar. This may or may not be appropriate depending whether you need to use the sugar later, or if you are planning on dissolving it. A quick reading would be fairly accurate. I'm assuming that the sugar will dissolve less readily in oils, but they may leave an inappropriate residue. Perhaps looking at the solubility in Toluene or Methylene Chloride.You can also calculate the specific gravity if you can get a weight in air and a weight in water. And from this you can calculate the volume.You could also crush some or all of it into a granulated form which might be easier to measure, or mix smaller and larger crystals and measure.
