A sample of a blue crystal was found at an industrial laundry facility outside of Albuquerque, NM. The only four elements possibly in the compound were determined to be C, H, N and O. Complete combustion of a 0.775 g sample of the unknown crystal with excess O2 produced 2.286 g of CO2, 0.702 g of H2O and 0.0728 g N2. The molar mass of the substance was found to be about 150 g/mol. What is the molecular formula of the unknown crystal? Use online resources to determine the most likely common name for this chemical. Please show your work for this problem to receive credit.
