Objective: In this laboratory investigation we plan to calculate experimental molar volume of a gas using the concepts of Dalton's Law and the Ideal Gas Law. We will therefore use the experimental and theoretical data to calculate a percent yield. Also, we can relate the mass calculated to the theoretical moles of a gas produced. Concepts: The overall concept throughout this lab were the gas laws. Gas laws deal with how gases behave with respect to pressure, volume, temperature, and amount. Boyle's law or the pressure-volume law ( P 1 V 1 = P 2 P 2 ¿ states that the volume of a given amount of gas held at constant temperature varies inversely with the applied pressure when the temperature and mass are constant. When pressure goes up, volume goes down. When volume goes up, pressure goes down. Avogadro’s law ( V 1 n 1 = V 2 n 2 ¿ gives the relationship between volume and amount when pressure and temperature are held constant. If the amount of gas in a container is increased, the volume increases. If the amount of gas in a container is decreased, the volume decreases. Furthermore, the ideal gas equation (PV=nRT) provides a valuable model of the relations between volume, pressure, temperature and number of particles in a gas. Procedure: (See Lab Handout) Data: In this experiment, we collected a volume of butane gas and used the ideal gas law equation (PV = nRT) to determine the molecular mass of the gas and the number of moles of butane gas.

    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.
