After months of work, you have synthesized an organic compound Wunderbarin (molecular weight = 254.5 g/mol)  believed to effectively treat Covid-19. Based on the reaction stoichiometry and the amounts of starting reactants the maximal amount of Wunderbarin you expect to get is 0.225 mol. Your chemical analysis of the product showed that you got 7.35 mL of pure liquid with density of 1.425 g/mL. What is the reaction yield in percent?
