Practice Problems: N = 6.02 x 10 23 R = 0.08206 L atm/mol K 1atm = 760 mmHg = 760 torr T(K) = T( o C) + 273.15 o C 1L atm = 101.325 J T( o F) = 9/5( o C) + 32 o F 1. What volume (in mL) will a sample of F 2 gas occupy in a syringe at 5.5 atm, if the F 2 has a volume of 25.0 mL at 1.2 atm? 2. To what volume will a sample of gas expand if it is heated from 50.0°Cand 2.33 L to 500.0°C? 3. A syringe initially holds a sample of gas with a volume of 285 mL at 355 K and 1.88 atm. To what temperature must the gas in the syringe be heated/cooled in order to have a volume of 435 mL at 2.50 atm? 4. What pressure will 14.0 g of CO exert in a 3.5 L container at 75°C? 1

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
