Histamine is a substance that is released by cells in response to injury, infections, stings and stuff that cause allergic responses, such as pollen. Histamine causes dilation of blood vessels and swelling due to accumulation of fluid in the tissues. People sometimes take antihistamine drugs to counteract the effects of histamine. A sample of histamine having a mass of 0.367 g is composed of 0.190g of carbon, 0.031g of hydrogen and 0.146 g of nitrogen. What is its empirical formula?
