3.a. Find the volume of the rubber stopper. Calculating the Volume of the Rubber Stopper Table view List view Calculation of volume by displacement Volume (mL) Water after adding the rubber stopper 59.0 Water before adding the rubber stopper 50.0 Rubber stopper 9.0 3.b. Determine the density of the rubber stopper by using the measured mass and the measured volume that was calculated in part a above. Mass of rubber stopper: 11.18 g (2.25/3pts) Measured density of rubber stopper (g/mL) 1.24 3.c. Using the density of the rubber stopper you recorded from the reference data as the reference value, calculate the percent error of the value of density of the object from part b above. Show your all work here. Reference data for Density of rubber stopper: 1.33 g/mL (4/4pts) Percent error, reported to one decimal place 9.8 3.d. Using your measured volume of the rubber stopper and the density of the rubber from the reference data, determine the mass of object (3/4pts) Calculated mass of rubber stopper (g) 12 (-1 pts) Recheck the number of significant figures that should be included. 3.e. Using your measured mass of the rubber stopper and the density of the rubber from the reference data, determine the volume of object. (0/4pts) Calculated volume of rubber stopper (mL) 9.0
