Conclusion Through logical reasoning it can be seen that it is actually more likely that the unknown alkali metal cation is potassium rather than rubidium. Potassium has a molar mass value lower than the experimental molar mass value. Even though the percent error value calculated using the molar mass value of potassium as the accepted value is 61.1 %, having an experimental molar mass value higher than the accepted molar mass value is more consistent with the possible errors that are likely to occur.

Unformatted text preview: It would be an unlikely situation for the experimental molar mass value to be lower than the accepted molar mass value. Although there are likely many errors present in this experiment and the results were shown to be inaccurate because of high percent error values, it can be concluded with greatest confidence that the alkali metal cation is potassium and the unknown nitrite salt is thus KNO 2....

    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.
