Object Weight in Air Weight in Volume Buoyancy (N) Water (N) Force (N) Displaced (mL) 250 g Hanging 2.5N 2.2N -0.3N 20 mL mass Rubber Stopper 0.3N .In -0.2N 7mL7. Use the experimental weight and volume of the rubber stopper to calculate the density of the stopper in kg/m' using the equation p = m/v. Use the measured weight and experimental volume to calculate density. Show your work. 8. Research the density of rubber stopper on the internet and compare your measured value of the density with the values listed online, using a percent difference. Make sure to include a citation for your reference. The density that I found on the internet is 1.522kg/m3 9. Does the data support Archimedes' Principle? Why or why not
