Quiz #1 Physics 230 Prof. Hadley 1. Question: NOTE : For the following problems, use these constants: R = 8.31 J/mol K = 0.082 atm L/ mol K, k = 1.38 X 10 -23 J/K, N A = 6.022 X 10 23 molecules/mol. STP means 0 deg.C, 1 atm (Use 0C = 273.2K) 1 atm = 1.013 X 10 5 Pa 1 amu = 1.66 X 10 -27 kg Also, pay close attention to significant figures. Question 1: If 35.0 L of Nitrogen at 25.0 deg. Celsius and an absolute pressure of 1.68 atm is expanded to 82.8 L and at the same time the temperature is lowered to -50.0 deg. Celsius, what will the new pressure be in atm? Your Answer:

    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.

    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.
