If you have a package of beans that weights 1 pound (454 g). You freeze dry and recover the 125 g of solid. What was the difference in mass? What percentage of your beans were made of this lost component. 5. In 200. g of beans, there are 30.5 g of carbs, 8.9 g of sugahs, of the beans? protein 8.3 g fiber, 15.4 g and 1.8 g of fat. What is the percentage of each of these parts of tExplanation / Answer
1. The reactants are converted into products in a chemical reactions. However, some of the reactants remain unused in the products and is left in the product. This excess amount of the reactant which is more than that is needed to complete the chemical equation increase the weight of the product and the total amount of material collected is more than the starting sample.
By eliminating the weight of the impurity additional excess reactant the discrepancy could be fixed.
