Write the molecular formula for the compound that exhibits a molecular ion at M+ = 84.091. Assume that C, H, N, and O might be present, and use the exact masses below:

Exact mass of carbon = 12.000

Exact mass of hydrogen = 1.0078

Exact mass of nitrogen = 14.003

Exact mass of oxygen = 15.995

(The order of atoms should be carbon, then hydrogen, then the others in alphabetical order. If there is more than one answer, just give one. )
