Refer to the following isolated scenarios during a UV/Vis experimental study on the acetic acid—m- xylene binary liquid-vapor equilibrium. While preparing/analyzing a mixture: m-xylene was contaminated with benzene, a more volatile substance with similar λmax. Vial used to prepare the mixture had traces of benzoic acid crystals. Cotton balls were wet with 10 drops of pure toluene instead of eight. When looking up data from the handbook, P* for p-xylene was mistakenly recorded instead of m-xylene. The recorded temperature was 25 °C but due to an undocumented AC failure, fell to 22 °C during the experiment. Acetic acid was contaminated with water. m-xylene was contaminated with ethylene, a very volatile substance with a single absorbance peak around 180 nm.

Question
Refer to the following isolated scenarios during a UV/Vis experimental study on the acetic acid—m- xylene binary liquid-vapor equilibrium. While preparing/analyzing a mixture:
m-xylene was contaminated with benzene, a more volatile substance with similar λmax.
Vial used to prepare the mixture had traces of benzoic acid crystals.
Cotton balls were wet with 10 drops of pure toluene instead of eight.
When looking up data from the handbook, P* for p-xylene was mistakenly recorded instead of m-xylene.
The recorded temperature was 25 °C but due to an undocumented AC failure, fell to 22 °C during the experiment.
Acetic acid was contaminated with water.
m-xylene was contaminated with ethylene, a very volatile substance with a single absorbance peak
around 180 nm.
