Experiment 1-Measurements and Density Prelaboratory Exercises 1. An object was carefully weighed on three different balances. Each balance was zeroed before weighing. The masses were: 10.35g,10.355g, and 10.30g. Calculate the average value of these measurements. (Please show all work and pay attention to significant figure rules.) 2. Us ing the average value to represe nt your true value, calc ulate the absolute error and percent error of each weighing found in question 1 . Show all work. 3. Initially 10.0mL of water was placed in a graduate cy linder and then a solid me tal was immersed in the water in the graduated cylinder. At this point, the volume of water was read as 15.5mL. If the mass of the solid is 9.25g, what is the density
