I chose this lab because I thought that this lab would be a good starting place for me moving forward. I learned where equipment was and learned how to use some of it. I was hoping to find out a little more on volume because, I struggle with that topic when it comes down to the math. I didn't really find it that difficult for me I had my peers to rely on and, Amanda was a big help to my group as well, she helped us a lot with our excel document. I felt that you needed to know how to use a scale, what water volume is when it's in a dry cup, and when its in a measuring cup. It wasn't really hard or confusing it was just a lot of work that needed to be done. Based on my data I can conclude that the volumetric flask is the most accurate piece of equipment out of the four my group and I have tested. I know this because the volumetric flask has the lowest percent error of all the equipment. The most precise piece of equipment is the volumetric flask. I know this because the R^2 value is the closest to 1 in the graphs I made in excel. The R^2 value represents the closeness of the measurement to one another so the most precise equipment must be the one with the a R^2 value close to 1. Based on my finding I can say that the volumetric flask will bring the best overall measurements. I feel this way because the volumetric flask was the most precise and accurate in my experiment; I also feel that the volumetric flask alleviates as much human error as possible. I feel the only thing that contributed to any inconsistencies or error were all human errors. I believe my group and I did all of our calculations correctly but we may have made mistakes while filling the instruments. It is very easy to make a mistake, you can't do everything perfect.
