This paper is a full determination for certain chemicals and their boiling points. It lists some already but given the atomic numbers of any material this project includes a conversion and calculation chart to find the freezing point of most any material. GOOD LUCK! Abstract: In this lab we determined the freezing point‚ and Kf‚ of pure 2‚4‚dichloralbenzne as well as a 2‚4‚dichloralbenzne/biphenyl solution. We used this information to determine the molar mass of an unknown (#24) by the 3rd step

In this study‚ three different methodologies have been employed for the determination of 226Ra by means of liquid scintillation technique. The first one (referred to as "Rn-LSC-28" hereafter and the tables and figures) is based on the method of Prichard and Gessel (1977) and Cooper et al. (1988) and also used by Escobar et al. (1996)‚ Zouridakis et al. (2002) and Aleissa et al. (2012). In this procedure‚ 8 mL of each standard solution was transferred to a high density polyethylene vial‚ covered with
