1. An object was carefully weighed on three different balances. Each balance was zeroed before weighing. The masses were: 10.35 g, 10.355 g, and 10.30 g. Calculate the average value of these measurements. (Please show all work and pay attention to significant figure rules.) 2. Using the average value to represent your true value, calculate the absolute error and percent error of each weighing found in question 1. Show all work. 3. Initially 10.0 mL of water was placed in a graduate cylinder and then a solid metal was immersed in the water in the graduated cylinder. At this point, the volume of water was read as 15.5 mL. If the mass of the solid is 9.25 g, what is the density?
