Chemistry 6A -- Practice Test -- Samples of some things that have not come up too much on midterms. You can assume that things on midterms or the other practice test might appear again. 1. A 20.0 g sample of gaseous hydrogen fluoride is dissolved in water to give 2.0 x 10 2 mL of solution. The concentration of the solution is: a) 1.0 M b) 3.0 M c) 0.10 M d ) 5.0 M e) 10.0 M 2. How many grams of salt are contained in 350 mL of a 0.250 M solution of NaCl? a) 41.7 b ) 5.11 c) 14.6 d) 87.5 e) none of these 3. What volume of 18.0 M sulfuric acid is required to prepare 16.5 L of 0.126 M H 2 SO 4 ? a) 11.6 mL b ) 0.116 L c) 232 mL d) 0.264 e) 1.16 L 4. How many mL of 0.300 M CaCl 2 solution is needed to prepare 240. mL of a solution that is 0.100 M in Cl - ? a) a ) 40.0 b) 80.0 c) 120. d) 240. e) none of these Consider the three reactions: I. Pb 2 + 2I - -> PbI 2 II. 2Ce 4+ + 2I - -> I 2 + 2Ce 3+ III. HOAc + NH 3 -> NH 4 + + OAc - 5.
