1. The problem statement, all variables and given/known data Hello, I'm looking for some help on how to perform some lab calculations. We recently did a lab on the Preparation of Geometric Isomers. We were preparing the Cis and Trans isomers of butenedioic acid, i.e Fumaric and Maleic Acid. The Maleic acid was done by reacting Maleic anhydride with water, and the Fumaric acid was obtained by using the maleic acid filtrate and a reflux apparatus with HCl. Here is the data I obtained: Maleic Anhydride Used: 4.99g Impure Fumaric Acid: 1.24g Pure Fumaric Acid: 0.82g Pure Maleic Acid: 0.78g 8mL was added to the anhydride and heated at the beginning I am supposed to calculate the theoretical yield for the experiment, but I cannot seem to find a balanced equation to use. I believe I am supposed to calculate the amount of product (fumaric+maleic) that can be produced from 4.99g of Maleic Anhydride. I also think that for every 1 mol of Maleic acid, there should be 1 mol of Fumaric produced (since they are isomers). 2. Relevant equations C4H2O3 + H2O →C4H4O4 3. The attempt at a solution Is this how I would go about it? C4H2O3 + H2O →C4H4O4 Calculate the amount of Maleic acid produced (using the anhydride as the limiting reagent), and since the fumaric is just an isomer, this should be the theoretical yield? Thank you for your help!!!
