Answer

a) $1.11\ g/cm^3$, ethylene glycol b) Yes

Work Step by Step

a) Mass of the sample: $16.08-12.20=3.88\ g$ Volume of the sample $3.50\ mL=3.50\ cm^3$ Sample's density: $\rho=m/V=1.11\ g/cm^3$ The closest density is ethylene glycol's. b) The density would be $1.1\ g/cm^3$, and although it would be technically possible to say it's ethylene glycol, acetic acid would be very close.
