42. * EXTENDED RESPONSE A mole is a unit of Element Mass of smole measurement used in chemistry. The masses of one mole of three elements are in the table. Hydrogen 1.008 grams a. A 100 gram sample of ascorbic acid contains Carbon 12.011 grams 4.58 grams of hydrogen. To the nearest tenth, Oxygen 15.999 grams find the number of moles of hydrogen. b. A 100 gram sample of ascorbic acid contains 54.5 grams of oxygen. To the nearest tenth, find the number of moles of oxygen in the sample. e. The ratio of moles of hydrogen to moles of carbon in ascorbic acid is 4:3. How does this ratio compare with the ratio of moles of hydrogen to moles of oxygen in ascorbic acid? Explain.
