D. Empty Volume Determination of Aluminum A sample of aluminum weighs 27.0 g and has a volume of 10.0 cm3. The atomic radius of metallic aluminum has been determined by x-ray diffraction to be 0.143 nm. There are 6.02 x 1023 total atoms in the piece of metal. 1. Calculate the volume of individual atoms assuming that atoms are spheres. 2. Calculate the volume of atoms in the sample 3. Calculate the volume of the empty space in the aluminum sample 4. Calculate the percentage of the empty space in the aluminum sample 5. What kind of unit will the aluminum sample have? Explain your answer.

C-lab Answer the following questions. You may upload a handwritten file if you like, as long as it is legible. Part A: Figure numbers refer to figures in the lab procedures. Do the calculations in the units given. 1. Very briefly explain how a photogate works. 2. How far would you go if you traveled at a speed of 30 miles per hour for 3 hours? 3. What acceleration would be needed to travel the same distance in the same time as in question 2 when starting from rest? What would be your final speed? 4. Refer to Figure 3. Given a track length of 90 cm and a height difference of 18 cm, what is sin 0 5. Draw the force diagram for an object on an inclined plane (see Figure 2 in the lab manual). Attach the diagram in question 2 below. What would be the acceleration given the inclination from question 4 and g = 9.8 m/s? Part B: Attach the free body diagram from question 5 above.
