![]() ![]() For a 1.0 molal solution of salt (containing 58.44 grams of salt per kg of water), the boiling point is raised by 1.0 degrees Celsius. The boiling point of salt water depends on the amount of salt added. Coffee and tea leaves contain a maximum of 5 of the caffeine in them. Melting point was determined in open-glass capillaries on a Gallenkamp melting point apparatus. Caffeine is found in common food and beverages that we consume every day, such as coffee and tea. The system name (IUPAC) was 1,3,7-trimethylpurine-2,6-dione, chemical formula C 8 H 10 N 4 O 2, molar mass 194.19 g/mol, density 1.23 g/cm 3, melting point.
