For example, the Celsius temperature difference t and the thermodynamic temperature difference T between the melting point of gallium and the triple point of water may be written as t = 29.7546 °C = T = 29.7546 K. I know impurities lower melting points so off that alone I would arrive at the conclusion that the unknown compound is m-nitrophenol. I have my doubts though because the mass of the crude compound was 0.41g however after recrystallization and vacuum filtration the mass of the sample was...
