Chemistry Structure and Properties
A thief uses a can of sand to replace a solid gold cylinder that sits on a
weight-sensitive, alarmed pedestal. The can of sand and the gold cylinder
have exactly the same dimensions (length $=22 \mathrm{cm}$ and radius $=3.8 \mathrm{cm} ) .$
a. Calculate the mass of each cylinder (ignore the mass of the can itself.. (density of gold $=19.3 \mathrm{g} / \mathrm{cm}^{3}$ , density of sand $=3.00 \mathrm{g} / \mathrm{cm}^{3} )$
b. Did the thief set off the alarm? Explain.
