How do you identify white sugar?

The most obvious answer, tasting it, is unfortunately off the table. There are many substances that look similar to sugar that would be very harmful if ingested.So how else can you identify a substance? Finding its density would be a good start. Measure a certain amount in a measuring cup, then find the mass of the mystery substance (Be sure to subtract out the mass of the measuring cup!).Divide the mass by the volume to get the density. For sugar, the density should be about 1.29 g/cm3Another way is to find the melting point of the mystery substance and compare it to the melting point of sugar. Slowly heat the substance until it begins to melt. (Putting it in a plastic bag and submerging it in hot water is probably the best way to do this.) Once it starts melting, use a thermometer to find it's temperature. If it is sugar, it should be around 170oC.

How would a substance with a density of 0.95 gmL behave when placed in both oil and water?

When two substances do not mix with each other, the less dense substance will float on the more dense substance. Vegetable oil floats on water. If the mystery substance with d = 0.95 g/mL does not mix with water, then it should float on top of water. If the mystery substance with d = 0.95 g/mL does not mix with vegetable oil, then it should sink in vegetable oil.
