Document Summary

Please keep your work covered and keep your eyes on your own paper! Cheating or any appearance of cheating will result in an f in the course and possible expulsion from the. A periodic table, formula sheet and the solubility rules are provided. You may rip these 3 pages off of the exam and use them to cover your work. Any scratch work should be on the back of the exam pages and should be handed in with your exam. Please show all work to receive partial credit. You have 80 minutes to complete the exam. C 71. 22g, 12 g/mole moles: 71. 22/12 = 5. 935 moles. N 13. 84 g, 14 g/mole: 13. 84/14 = 0. 9886 moles. H: 100g-71. 22g-13. 84g = 14. 94 g, 1g/mole: 14. 94/1 = 14. 94. Divide each by smallest number of moles in hopes of getting whole numbers: P =435 torr/760 = 0. 573 atm ncxhynz=pv/rt = 0. 573*0. 15/(0. 08206*423) = 2. 476x10-3. Mm = g/mole = 250x10-3 g/2. 476x10-3 moles = 100. 96 g/mole.
