Do not round any intermediate calculations.
Note: Your answer is assumed to be reduced to the highest power possible.
Your Answer:
In the opening scene of the movie Raiders of the Lost Ark, Indiana Jones tries to remove a gold idol from a booby-trapped pedestal. In an effort to remove the idol without tripping the trap, he replaces the idol with a bag of sand of approximately equal volume. The density of gold is 19.32 g/mL and the density of sand is about 3 g/mL.
A) If the idol had a volume of 1.5 L, what volume of sand would be required to provide the same mass as the same sized idol made of gold?
B) In a later scene, Indy and an unscrupulous guide play catch with the idol. Assume that the volume of the idol is about 1.5 L. If it were made of solid gold, how many pounds (lb) would it weigh?

He counts out 5 BBs and finds their total mass to be 1.9 g. He also finds the total mass of the stock container and the BBs to be 239.3 g and the mass of an identical, empty stock container to be 115.8 g. The store manager then uses his data to calculate the number of BBs in the stock container: Average mass of one BB = 1.9/5 = 0.4 g Mass of BBs in container = 239.3 g - 115.8 g = 123.50 g Number of BBs in container = 123.50/0.4 g= 300 BBs (a) Evaluate the manager’s calculations with regard to significant digits. If necessary, rewrite any steps, recalculating with the adjusted quantities. For any step that you have to rewrite, explain why the manager’s calculation is in error.
