Measured Average Mass   =    total mass of mix        total # beans used Data Table 3 Mass of mix of beans (g) Total # of beans used Average Mass of Beanium (g)                           ( TRUE VALUE ) b. Calculate the % error using the calculated mass of one particle  of Beanium (experimental value) as compared to the measured  average mass of a particle of Beanium (true value). % Error  =     Experimental Value – True Value     x 100   True Value % Error  =     (                     )                  (                                   )         x 100  =                      %     (     ) QUESTIONS: 1. Was the calculated mass of Beanium equal to the measured mass of Beanium? Explain  any discrepancies. 2. Based on what you observed in this activity, explain why the atomic masses for most  elements are not whole numbers as you would expect from the mass numbers of each  element.

### What students are saying

• 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.
