I performed a laboratory experiment using a Dumas bulb to find the molar mass of an unknown, clear liquid in order to identify it. The Dumas bulb was submerged in a beaker filled with water (with the tip out of the water) and the water was boiled to evaporate the sample. I eventually got a result with 38.1 g/mol as the mean, with a huge confidence interval (at 95%) of +- 18.1 g/mol. This is because I screwed up my 3rd trial so I could only use my first 2. I got results of 36.72, 39.56, and 49.11 g/mol. I need help identifying this liquid. The liquid is clear, safe to inhale in vapor form (I'm still alive), does not have a distinct smell, has a boiling point lower than 100 degrees C, and is not "an exotic compound". Edit: I'm now deciding between ethanol and methanol. I'm hearing that methanol is poisonous in vapor form, so I think it may be ethanol.
