include decimals, the selected glassware does not require those smaller increments. Now if one was to measure 38.50 mL of water, the 50 mL burette would be the best instrument, seeing that it is most accurate, with an average percent error of 3.5833. This particular piece of glassware is best for measuring out a volume of water to the decimal place. Conclusion: The goals of this lab were to use the calculated average percent errors of the various glassware to determine which is most accurate and/or precise in measuring the volume of a liquid, and to use the TARE button on the electronic balance to measure out 1 gram of sand. Both goals were adequately met, resulting in a fairly successful investigation. In conclusion, should a scientist wish to accurately measure the volume of a liquid he/she should utilize the 50 mL burette, since it has the lowest average percent error of 3.5833%. Should the scientist wish to precisely measure the volume of a liquid, he/she should utilize the 50 mL beaker, since it has the lowest range of 0.8159 between the three calculated percent errors.
