A cup of pure green tea usually contains around 25 milligrams of caffeine per 8-ounce serving. This is considered to be a low amount of caffeine.

In this case we divide by 2. C_4H_5N_2O This is the Empirical Formula. I hope this was beneficial. SMARTERTEACHER Caffeine - Aku Takkan Memiliki. C Am C Am.
