1. Calculate the volumes of the samples used in Procedure step 2. Record the calculated volumes in Table 2.2. Why could we not find the volume of the bolt by this method? 2. How did you find the volume of the PE rod using the displacement method? Note: 1 cm3 = 1 mL. Because PE floats, push the rod under the water with a very small object, such as a pin, and volume of the pin is negligible and can be ignored. 3. Except for the bolt, note the difference between the calculated volumes and the volume found by the displacement method. Which method is more accurate? Why?
