WebFeb 27, 2024 · The freezing points away solutions are all lower than such concerning the pure solvent. The freezing point depression is directly proportional to one molality is the solute. The thawing points of solutions are all lower then that of the purified solvent. The thawing point signs are directly proportionally in the molality to and solute. Urea, also known as carbamide, is an organic compound with chemical formula CO(NH2)2. This amide has two amino groups (–NH2) joined by a carbonyl functional group (–C(=O)–). It is thus the simplest amide of carbamic acid. Urea serves an important role in the metabolism of nitrogen-containing compounds by animals and is the main nitrogen-containing substance in the urine of mammals. Urea is New Latin, from French
