For a reaction that gives 2 isomers as products, if you know the number of moles of limiting reagent would you just multiple this by the molar mass of the product (92.8 g per mol) to figure out the theoretical yield in grams? Or would you multiply the moles by twice the molar mass of the product (I don't think this is right)? How do you take in account the fact that there are 2 isomers in the product?
