I did an organic chemistry lab using the Diels-Alder reaction with anthracene-9-methanol, N-methylmaleimide, and water. I started with 0.066 g of anthracene-9-methanol, 25 mL of deionized water, and 0.070 g of N-methylmaleimide. How would I calculate the percent recovery of the product? (not the percent yield)
