a) Calculate the theoretical yield of your product. The theoretical yield should be quoted as a mass, not a number of moles. Units must be shown on all numbers that need them. Calculations that are done with an incorrect number of significant figures will be counted as incorrect. Your work must be shown. b) Calculate the percent yield for your product. This calculation should be done with masses of your product and the theoretical yield, not the number of moles....

Which statement is correct in regards to percent yield and theoretical yield? Percent yield determines the maximum amount of product that can be expected through mathematical calculations. It is set as a proportion to the actual yield to compute the theoretical yield. Together, they are used to determine the reactant that will limit the reaction. Percent yield determines the maximum amount of product that can be expected through mathematical calculations. It is then used to compute the theoretical yield. Calculating...

How would I find the theoretical and percent yield of a Fischer esterification? I used 1.5 mL of 1-pentanol (MW: 88 g/mol ; Density= 0.811 g/mL) and 3 mL of glacial acetic acid (MW: 60 g/mol ; Density= 1.06 g/mL). This gave the formation of pentyl acetate (MW: 130.19 g/mol). The crude product was 1.006 g and the distillation product was 0.19 g
