Jones 1 Caleb Jones Chem Lab 114 Density and Graphing In this experiment our goal was to prove the density of water, and to explore the accuracy and precision of several measuring devices. The known density of water at 25 O C is 1 g/mL. For each measuring device used in the experiment we measured three different amounts of water three different times. This accounted for 27 different meas- urements and each one was weighed individually. Then the density of water was calcu- lated for each measuring device. Then the accuracy and precision for each device was considered. The experiment was started off by measuring water in a 50 mL beaker. The first volume measured was 5 mL. The scale was tared to the weight of the beaker and then the water was poured into the beaker to 5 mL and weighed on the scale. This process was repeated two more times. Then 10 mL was poured into the beaker and the weight was recorded. This process was also repeated two more times. Then 15 mL was poured into the beaker and weighed three different times. After each weight the water was poured out, the beaker was dried, and the scale was tared to the weight of the
