Results and Discussion: The experiment was implemented in order to identify the identity of an unknown nitrate salt (with a formula of MNO 2 , where M + is the alkali metal cation) by using the stoichiometric relationships found in the Ideal Gas Law. To determine the identity of the unknown nitrate salt, the unknown nitrate salt was dissolved in sulfamic acid shown with the following chemical reaction: MNO 2 ( aq ) + HSO 3 NH 2 ( aq ) MHSO 4 ( aq ) + H 2 O ( l ) + N 2 ( g ) (1) This reaction caused N 2 gas to form, which was the main component in the experiment to determine the identity of the unknown nitrate salt. The unknown nitrate salt was given a number of : 3285 . Using the Ideal Gas Law, PV=nRT, and the calculated values for each of the components of the Ideal gas law, the number of moles of the nitrogen gas was determined: Pressure, P, was determined using the known relationship of Dalton’s partial pressures, and the knowledge that the total pressure, P total , was the pressure of the room at the time of the

    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.
