In March 2007 a number of pets were sickened or killed by pet food contaminated with the chemical melamine, which is used in the manufacture of certain plastics. It is thought that the melamine was added to make a pet food additive appear to have more protein than it really did. Melamine is 28.57%C, 4.80%H, and 66.63%N by mass. If the molecular weight of melamine is 126.15 g/mol, what is its molecular formula?
