Thomas Edison State CollegeGeneral Chemistry I with Labs (CHE-121)Section no.: OL009Semester and year: Feb2019Written Assignment 6: GasesAnswer all assigned questions and problems, and show all work. 1A gas occupying a volume of 725 mL at a pressure of 0.970 atm is allowed to expand at constant temperature until its pressure reaches 0.541 atm. What is its final volume?(5 points)2The 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)3Why 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)
