A bar of gold with a mass of 2060.5 g has the following dimensions: 7.30 cm by 3.25 cm by 4.50 cm. Use this information to calculate the density of gold in g/mL. (Note: 1 cm3 = 1 mL) 1. 2. Would the density value you just calculated be different if the size of the gold bar was different, or if the gold took the shape of a statue instead of a bar? Explain.

Convert the mass of the statue into pounds. (1 kg = 2.205 Ib) Note how Indiana Jones picks up and holds the statue from the pedestal. Do you believe that the statue actually weighed as much as you just calculated in the previous question? Why or why not? 6. 7. Indiana Jones was trying to replace the statue with a bag of sand that had an equal mass. What should be the volume of the bag of sand (in mL) if it is the same mass as the statue? Convert your answer to question 7 (above) from ml to L. Use dimensional analysis and show your work! 8. From your answer to question 8 (above), how many 2-liter soda bottles is that volume equivalent to? (Don't round to the nearest whole number) Did the bag of sand appear to be as big as this? Provide possible logical, realistic explanations that would explain the discrepancies between what you saw and what you calculated (don't just say "it was a movie!" or "it was make-believe!"). 10. 5. 9.

Would the density value you just calculated be different if the size of the gold bar was different, or if the gold took the shape of a statue instead of a bar? Explain. 2. To determine the density of sand, you put a graduated cylinder on an electronic scale and zero it. Then, you pour 7.50 mL of sand into the graduated cylinder. The scale reads 9.800 g. What is the density of the sand? 3. Assume the volume of the statue in the movie is 1.000 L. Use the density of gold to calculate the mass (in kg) of the statue. 4.
