Yes, it certainly does, although not necessarily the same volume it did when it was a solid. When you add sugar to water and dissolve it, the volume of the sugar water will be greater than the volume of the water before you added it.
You can determine how much the volume changes by just measuring the volume before and after adding sugar and taking the difference. However, note that upon adding sugar to water and dissolving it, you can't treat it like "dissolved sugar" and "water" separately. They are now a solution and you can't really separate the volume of sugar molecules unless you talk about molecular size and Van der Waals radii and other complicated effects when water interacts with solutes on a molecular level. So while the volume will certainly change when you add sugar and dissolve it in water, exactly what amount of that change is due to the molecular size of sugar molecules and what is due to other effects is difficult to determine exactly.
* Sucrose's concentration is 4.636 M: (1587 g/L)/(342.2965 g/mol). * Water's concentration is 55.51 M: (1000 g/L)/(18.0153 g/mol) * 2.5 M of solution is 1316.3 g/L. Its molar fraction is .04156 M/M: 2.5/4.636+55.51. * The density-guess would be 1024.4 g/L: .04156(1587 g/L)+.95844(1000 g/L). The solute's proper volume is thus 2039.2 g/L: (1587 g/L)(1316.3 g/L)/(1024.4 g/L). Of course it does; all materials take up volume, other than fictional objects such as black holes. They like each other, so they shrink.
yes of course it has, because when you evaporate the solvent you will see the salt remaining under it! try it! dissolve some table salt in water, then boil it or leave it under sunlight for 3 to 4 days. if you boil it, small salt crystals are found, if you evaporate them under sunlight, big crystals are obtained. enjoy your easy experiment :P
The mass of both solute and solvent are conserved (sugar water weighs the same as the sugar plus the water), the volume of the solution increases less than the dry volume of the sugar, so the density of the solution is higher than water.
No, when sugar is dissolved in water, it does not form a new substance. The sugar molecules are simply dispersed and mixed with the water molecules.
When sugar is dissolved in water, the volume increases slightly due to the spaces between water molecules filling with sugar molecules. However, this increase is typically negligible for practical purposes since sugar dissolves readily in water.
The addition of 5ml of sugar to 250ml of coffee should increase the total volume to 255ml, not remain at 250ml. Mixing two substances typically leads to an increase in total volume due to the added volume of the sugar.

The exact number of sugar cubes that can be dissolved in cold water depends on the size of the sugar cubes and the volume of water, but generally speaking, you can dissolve 1 sugar cube per 1 ounce of cold water. Keep in mind that the solubility of sugar decreases as the water temperature decreases.
The resulting solution is called a sugar solution or sugar water.
The volume of water will increase slightly due to the dissolved sugar molecules taking up space in the solution. However, the change in volume will be minimal because the amount of sugar is relatively small compared to the volume of water.
The sugar is the solute and the water is the solvent. Whatever is dissolved is the solute, and whatever the solute is dissolved in is the solvent. The solvent dissolves the solute.
This is the movement of molecules.
The solute.
