Chemistry 1211 Practice Exam II Name__________________________ This practice exam is designed to be similar to a second exam for the course. You should attempt this exam without the use of notes, books, or help and you should time yourself, although this practice test is probably longer than the real exam. When finished, grade your exam using the exam answers, but do not look at the answers before you attempt the exam. You should then be able to tell how well prepared you are for the second exam of your course. Use this as an evaluation tool to help you decide on areas that may need more study time. Good luck, let me know if I can be of any assistance. DATA The first part of the exam consists of 50 multiple choice questions. 1. What is the molarity of a solution prepared by mixing 9.5 g C3H8O3 (MW = 92) with enough water to have a total volume of 31.5 ml? a. 0.10 M b. 0.40 M c. 3.3 x 10-3 M d. 3.3 M e. 300 M 2. A pressure of 1.00 atm is the same as a pressure of: a. 193 mm Hg b. 101 torr c. 760.0 mm Hg d. 760 in Hg e. 29.92 torr 3. What is the result of mixing solutions of sodium sulfate with lead (II) nitrate? Data: lead (II) sulfate is a solid. a. Na2SO4 (aq) + Pb(NO3)2 (s) b. NaNO3 (aq) + PbSO4 (g) c. NaNO3 (aq) + PbSO4 (s) d. NaNO3 (s) + PbSO4 (aq) e. It is not possible to tell from the information given. 4. A sample of gas (24.2 g) initially at 4.00 atm was compressed from 8.00 L to 2.00 L at constant temperature. What is the new gas pressure?
