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. 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.

please sigh which one is which one

Transcribed Image Text: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!").
