    the foil .0031 Part D 1. Boiling point of the ethanol 65ºc Part E 1. T¹ initial temperature 125ºc 2. T² final temperature 155ºc Post lab questions: 1. Based on my temperature value and my lab measurements‚ I calculated that the water density would be 2.16 (g/mL). This calculation of density does not match up with the density in the table provided. The table calculations would give the water with 22ºc a density of 0.99770. My calculation or lab measurements must be wrong because

    MELTING POINT AND BOILING POINT OF ORGANIC COMPOUNDS ------------------------------------------------- ABSTRACT The melting point (MP) and the boiling point (BP) are probably the most widely used physical constant in the field of science. Determining the boiling point and the melting point of a compound helps you to characterize an unknown solid in a quick‚ easy and cheap way. The temperature at which a compound turns from a solid state to a liquid state is known to be the melting point. On the
