The solubility of sugar, or sucrose, in water varies with temperature, ranging from 179 grams per 100 milliliters at 20 degrees Celsius to 487 grams per 100 milliliters at 100 degrees Celsius. As temperatures increases, the solubility also increases.
Sucrose is quite soluble in water and methanol. However, its solubility in ethanol is very slight, while it is insoluble in ethyl ether. Sucrose and water both are covalently bonded compounds. This is the reason why sugar dissolves in water
Table sugar has the molecular weight of 342.29648 grams per mole, and its chemical formula is C12H22O11. Sugar's density is 1.5805 grams per cubic centimeter.
