Unformatted text preview: weight of 13.54 oz and Brenda would get a weight of 13.82 oz thus making Brian’s balance more accurate. 3. (a) In Part B we will make three weighings at least. (b) i. I expect for the grauduated cylinder to weigh slightly more in part five than when it was perfectly dry because they may be some precipitation left after dumping the water. It didn’t say to dry out the cylinder completely so I would imagine it would weigh more. ii. I plan on using the same analytical balance for all five weighings because that would lead to more accuracy and precision. If I use a different scale for one of the measurements the numbers may not make sense and be true to the experiment. Although it is unlikely, using a different balance may throw off the whole experiment....
