My lab partners and I did not deviate very far from the required procedures. However, we did have our faults. In regards to the aluminum atom experiment, we attempted to cut a perfectly square piece of aluminum foil, but that was very difficult. Our square of aluminum foil was nowhere near being a perfect square. Nonetheless, we still used the equation for the area of square (A = s2) in order to find the area of the aluminum foil. Thus, the area of the aluminum was unreliable. Also, the weight of the aluminum foil could also be considered uncertain because the digital balance that we used to measure the weight could never be perfectly precise in how it was set. Moreover, I do not think that my group put exactly 10 mL of water in the volumetric…show more content…
Lastly, rounding was a primary deviation in both the water and aluminum experiment. The overuse of rounding possibly led to a significant deviation in our final results for the cost of both a single atom of water and aluminum. I predicted that my results for both the cost of one single atom of aluminum and molecule of water will be an immensely microscopic number. I assumed that the number will be from around 4 to 10 dollars multiplied by 10 to a negative exponent ranging from 20 to 25 in the units of dollars per atom, making the cost microscopic. My hypothesis was correct. The cost of one single atom of aluminum was \$4.10 · 10-25, while the cost of one single atom of water was \$8.68 · 10-26. My prediction was extremely close to the range of possible costs that I anticipated. My hypothesis arose from the fact that atoms and molecules are immensely small. If the size of molecules or atoms was tiny, than the cost of one single atom of aluminum and molecule of water must be extremely small as well. Therefore, my connection between the size and cost of a single atom and molecule must have been accurate because my hypothesis was correct. As a result, I learned from this experiment truly how atomic an atom or molecule is. I now have a better image of how tiny a molecule or…show more content…
Nonetheless, we still had our errors. Pertaining to the aluminum atom experiment, we endeavored to cut an ideally square piece of aluminum foil. Yet, that was very tricky. Our square of aluminum foil was not a model square. However, we still utilized the equation for the area of square (A = s2) in order to find the area of the aluminum foil. Therefore, the area of the aluminum was erroneous. Also, the weight of the aluminum foil could also be considered uncertain because the digital balance that we used to measure the weight could never be perfectly precise in how it was set. Moreover, I do not think that my group put exactly 10 mL of water in the volumetric flask in regards to the water molecule experiment. Lastly, rounding was a primary deviation in both the water and aluminum experiment. The overuse of rounding possibly led to a significant deviation in our final results for the cost of both a single atom of water and
