Determine the limiting reagent and calculate the percent yield. Melting Point: 27-30 oC Final product (trans-9-styrylanthracene) mass: 0.28 g Benzyltriphenylphosphonium chloride (Hygroscopic) mass: 0.98 g/388.87 g/mol = 0.0025201 9-Anthraldehyde 98% mass: 0.52 g / 206.24 g/mol = 0.0025213 50% aqueous sodium hydroxide volume: 0.0013 L/18.9375 mol/L=0.0000686 (limiting) Moles Benzyltriphenylphosphonium chloride (Hygroscopic): 0.98 g / 388.87 g/mol = 0.0025201 Moles 98% 9-Anthraldehyde: 0.52 g/206.24 g/mol = 0.0025213 Moles 50% aqueous sodium hydroxide: 0.0013 L / 18.938 mol/L = 0.0000686 (limiting reagent) Theoretical yield: 0.0000686 moles Product (trans-9-styrylanthracene) moles: 0.28 g/280.4 g/mol = 0.0009986 Percent yield: 0.0009986/0.0000686 = 1456 %
