4. Post-lab Report for Synthesis of Acetanilide Fill in the table below. All molecular weights reported to two decimal places (hundredths place)- and densities reported in full-are to be gotten from Wikipedia only. If not listed in Wikipedia, then use PubChem. The amounts for the reagents used and their properties are to be followed by the appropriate unit with a space in between (e.g. 45 mg, 0.62 mL, 145.35 g/mol). Entries in the table must be typed to receive credit. NO RED INK. Reagents Volume of acetic anhydride used Density of acetic anhydride Molecular weight of acetic anhydride Volume of aniline used Density of aniline Molecular weight of aniline Mass of acetanilide recovered Molecular weight of acetanilide Experimental amounts used with units 1.5 mL 1.08 g/cm³ 102.09 g/mol 1.0 mL 1.02 g/cm³ 93.13 g/mol 0.812 g 135.17 g/mol Questions: You may do questions 1-7 by hand. Use the density and molecular weight values reported in the table, in full, only. NO RED INK. 1. Calculate the mass of acetic anhydride used to 4 sig. figs. (must show all work). 2. Calculate the mmol of acetic anhydride used to 4 sig. figs. (must show all work). Page 1 of 2
