Mass of lauric acid is 5.103g

Determining the f.p of a solution of lauric acid with an unknown: Mass of unknown + lauric acid + apparatus = 22.9483 g Mass of unknown = 0.8343g Data recorded every 1min for the solution: Time (min) Temperature (C) 50 2. 49 48 4 47 46 6. 44 7 42 40 38.5 10 38.5 11 38 12 37.8 13 37.8 14 37.7 15 37.7 Graph the data in the table as above in Part A. and determine the f.p of the solution. 5. Determine the AT,. AT= T, (solution) - T (solvent) 6. Using the equation AT: = molality x molal f.p depression constant for lauric acid Determine the molality of the solution. 7. Using the examples and video determine the molar mass of the unknown. Additional information about the unknow is it has mass composition of 68.84 % C 4.96 % H 26.29% O Use this to identify the compounds molecular formula.
