Arghaya Dalapati I2 Conclusion The purpose of Part A of the experiment was to determine the ideal gas constant R, .08206 L atm/mol K, through experimentation. There were .025 grams ( 9.20E-04 moles) were reacted with NaOH in a burette to generate hydrogen gas, which will be reacted to generate the gas constant R. When the experiment was first started the Initial Volume of the burette was 45.70 mL, and after experimentation the Final Volume was 11.80 mL, thus .034 Liters. From basic stoichiometry, it was founded that from 9.20E-04 moles of Aluminum, 1.38E-03 Moles of Hydrogen were created. The room pressure was found to be 29.03 inHG, which convered to .97 atm. The room pressure is unquie since it contains all the partial pressure of hydrogen gas, air and water vapor. The partial pressure of Air can be assumed negligible since it is so small, but the partial pressure of water vapor has to be considered. The room temperature was founded to be 20.00 thus the pressure of water in ATM was determined to be .02.

    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.
