Chapter 1: Measurement InstrumentsAlma RomeroMay 29, 2018(Lab Partners- Martin Alvarez, George Said, Alex Votypka, Enock Jean)IntroductionThe purpose of the experiment is to show how to use the different measuring tools can affect theprecision of the data. Also, to learn how to use the concepts of the significant figures, the experimentalerror and some methods of error and data analysis in your experimental measurements.TheoryThe equation is to determine the volumes of the calculated measurementsρ =MVwhere m is the in kilograms, V is the volume in cubic meters, and ρ is the density in units of kilogram percubic metersFor a cube the volume isV=LWHwhere L is the length, W is the width and H is the height.The equation that shows percent errorPercentage Error=[ApproximateValueExact Value][Exact Value]x100Where the approximate value is the number of all the pages and the exact value was only the 10 pages,from there we could get the percentage errorProcedures1.We first started by measuring the metric stick, the Vernier caliper and the micrometer caliperalso the beaker to figure out the least count and the estimated fraction and figuring out themeasurements of them
2.We started measuring just one single piece of paper from the lab manual and we did it four
