  • 1. Define the following terms (15 points) (a) STP (b) molar volume (c) Avogadro’s number (d) Charles’s Law (e) empirical formula 2. Sucralose, the sweetener commonly found on Splenda® has a chemical formula C12H19Cl3O8. What is the percent of chlorine present in sucralose? (10 points)
    User_18773 | Nov 25, 2018, 20:18 PM
  • 3. Mass / mole relations (20 points) (a) How many moles of aspirin (C9H8O4) are in a 325 mg tablet? (b) How many grams of propane (C3H8) do 1.27 x 1024 molecules weigh? (c) How many formula units of sodium chloride are present in 1.200 moles of NaCl? (d) What is the mass in grams in 3.25 L of N2 gas at STP?
    User_18773 | Nov 25, 2018, 20:18 PM
  • 4. Epinephrine (adrenaline), a hormone secreted into the bloodstream in times of danger or stress, contains 59.0% C, 7.1% H, 26.2% O, and 7.7% N by mass. (a) Find the empirical formula. (b) If the molar mass is approximately 180 g/mol, find the molecular formula. (15 points) 5. What is the density of chlorine gas, Cl2, at STP? (5 points) 6. A 5.12 L volume of ethane gas is stored at a pressure of 752 torr. Calculate the volume it occupies if the pressure is increased to 1410 torr while the temperature remains constant. 7. A scuba diver’s tank contains 290.0 g of O2 compressed into a volume of 2.30 L. Calculate the gas pressure inside the tank at 9.00 °C. (10 points)

  • 8. Nitroglycerin (C3H5N3O9) is a powerful explosive. Its decomposition may be represented by 4 C3H5N3O9 → 6 N2(g) + 12 CO2(g) + 10 H2O(g) + O2(g) This reaction generates a large amount of heat and many gaseous products. It is the sudden formation of these gases and their rapid expansion that produces an explosion. (a) What is the amount of oxygen obtained by the reaction of 200.0 grams of nitroglycerin? (b) If the amount of oxygen produced was found to be 6.55 g, what is the percentage yield? Molar masses: C3H5N3O9 = 227.09 g/mol; O2 = 32.00 g/mol. (15 points) Bonus: (10 points) Consider the reaction: MnO2(s) + 4 HCl(aq) → MnCl2(aq) + Cl2(g) + 2 H2O(l) If 16.5 g of MnO2 and 20.2 g of HCl react, (a) what is the limiting reactant?, (b) how many grams of water are produced. Molar masses are as follows: MnO2 = 86.94 g/mol, HCl = 36.46 g/mol, H2O = 18.02 g/mol.

  • 25 questions
    User_18773 | Nov 25, 2018, 20:32 PM
  • Example: Answer No. 8 2.00 x 102 g *(1 mol C3H5N3O9)/(227.1 g C3H5N3O0)* (1 mol O2)/(4 mol C3H5N3O9) * (32.00 O2)/(1 mol O2) = 7.05 g Actual yield= (Actual yield)/(Theoretical Yield) * 100=6.55 g/7.05 g *100=92.9%
