A sample of a blue crystal was found in John's car. The compound is believed to be acontrolled substance. Robert, the crime lab technician, performed preliminary analysisand determined that the compound contains four elements C, H, N, and O. Robertasked you to analyze the data and determine the molecular formula for thecompound. The molar mass of the substance was found to be about 311 g/mol. Whatis the molecular formula of the unknown crystal?
