You can use the percent error to find the accuracy of each glassware, therefore you can compare each glassware to each other. The measurement labs reveals that the beaker produce results closest to the actual value, which means it is the most accurate, while the erlenmeyer flask results revealed it was the least accurate of the three- look at column six "Accuracy(Percent Error)".
2B.Which Glassware had the smallest precision and the largest precision?
You can use the equation for standard deviation to measure the precision then you can compare the precision from each glassware to each other. The graduated cylinder produces results that are the most consistent, therefore the most precise, …show more content…
If it 's important to measure the same value each time, then the graduated cylinder exists as the best tool to measure.Also, the graduated cylinder works well with small measurement The erlenmeyer flask exists as very useful when it come to measure large amounts, not very useful for small, because it doesn 't start labeling until 10 mL. Also, the beaker and flask are more useful for containing and hold chemicals, while the graduated cylinder is better for delivering and measuring.3A. The results of my experiement contradicted my prediction because I thought that the graduated cylinder would be the most accurate because it inlcudes more increments to measure. To my surprise the beaker was the most accurate. Although I didnt predict that the beaker would be the most accurate, I thought it would be the most precise. The flask being the most accurate was out of the question because the flask doesnt start measuring until 10mL, therefore small volumes would not be measured accurately.In addition, I saw the beaker and flask as glassware to simply hold chemicals, so having the beaker be the most accurate was …show more content…
Knowing the accuracy and precision of the intended glassware to use is important because it has an affect on the overall results and depending on the purpose of the experiment, depends on which glassware exists as the best to use. For example,based on the results, If I was trying to measure how much of a solution is required to react with another solution and I was using a pipet to transport the liquid, I would uses a beaker because when I go back to measure the difference of the solution left, it would be the most accurate. The graduated cylinder would be the most precise, so if I was trying to find how much of the solution on average it takes, the graduated cylinder would be the best glassware. Also, know the accuracy and precision of the glassware allows you to know what is going on in your experiment. If you were measuring something and your data kept being off, you would know its because of the accuracy and precision of the glasware and account for that, so you dont have wandering
