Identifying an unknown hydrocarbonIs it possible to identify what the hydrocarbon is with just knowing the volume of it (9.61 ml), the mass (7.669 g/ml), density (0.798 g/ml)? Under tensor lamp, in ambient light, and in dark light there was no color noticed. It smelled somewhat like gasoline maybe and was smoky as far as combustion characteristics. Boiling point is unknown.
Possibly identified as Cyclohexene.
Can you identify what this may be and what the boiling point should be of the hydrocarbon?
