- Homework Statement
- Determine the mass of one marble and the container, given the mass of 10 different containers that contain an unknown number of marbles in them. After finding the mass of one marble, and the empty container, use this data to find how many marbles were in each container.
I then have to answer these questions
- Would having more containers make this easier?
- Would having a large variety of quantity make this easier?
- How does this relate to Millikan's experiment?
- What are some sources of error?
- Relevant Equations
- I don't believe I require any equations to solve this problem except the average one:
Average = sum of numbers/number of numbers
I arranged the masses in ascending order:
11.0 g
11.1 g
20.6 g
21.4 g
21.5 g
25.7 g
25.8 g
25.9 g
31.6 g
31.9 g
I found the average mass of the marbles: 22.65 g
I found the difference in masses of the marbles:
0.1 g
9.5 g
0.8 g
0.1 g
4.2 g
0.1 g
0.1 g
5.7 g
0.3 g
I found the average of the differences: 2.32 g
I subtracted both the averages to find the mass of one marble: 20.33 g. This doesn't make sense since the smallest mass of a container + the marbles = 11.0 g. A single marble on its own can't be 20.33 g. Some additional info I got was that there is a maximum of 5-6 marbles in one container and the empty container weighs at least 3 g.
I would really appreciate help on where I went wrong and how I can go about answering the rest of the questions. Thank you!
