Splet18. apr. 2024 · From the molecular formula, C6H12O6, one can find there are 6 carbon atoms, 12 hydrogen atoms and 6 oxygen atoms in one molecule of glucose. Molar mass of C6H12O6= (6x12) + (12x1) + (6x16) = 72 + 12 + 96 = 180 g mol-1 Now we can calculate the number of moles of glucose as follows: It is also possible to get the number of molecules … SpletThe mass percent of carbon in pure glucose, C6H12O6, is 40.0 percent. A chemist analyzes an impure sample of glucose and determines that the mass percent of carbon is 38.2 …

Which of the following impurities could account for the low mass percent of carbon in the sample? SpletAlthough this was a very basic experiment I found that the five- percent concentration was quicker at producing 2ml of CO2 than the three- percent concentration. In this experiment I used 5 grams of yeast in both concentrations. The basic method for my experiment is as follows: 1 I will change the percentage of glucose concentration in the yeast. childhood friends to lovers kdrama
