Name: John Hendrie College ID:0571667 Thomas Edison State University General Chemistry I with Labs (CHE-121) Section no.:010 Semester and year: Jan2018 Written Assignment 6: Gases Answer all assigned questions and problems, and show all work. 1.A gas occupying a volume of 725 mL at a pressure of 0.970 atm is allowed to expandat constant temperature until its pressure reaches 0.541 atm. What is its final volume? 2. The volume of a gas is 5.80 L, measured at 1.00 atm. What is the pressure of the gas in mmHg if the volume is changed to 9.65 L? (The temperature remains constant.) (5 points) (Reference: Chang 5.21) 5.80 L = P2 x 9.65 L 5.80 / 9.65 = P2 P2 = .601 .601 x 760 = 456.788mmHg 3.Why is the density of a gas much lower than that of a liquid or solid under atmospheric conditions? What units are normally used to express the density of gases? (5 points) 4. A sample of nitrogen gas kept in a container of volume 2.3 L and at a temperature
