Question

Use Archimedes’ principle to prove whether or not the king crown is made up of gold. You found that a king’s crown whose mass is (a) 9.28 kg has an apparent mass of (b) 6.18 kg when submerged in water. (The density of pure gold is 1.932x 104 kg/m3).




a.
Density of gold is 1.932x 104 kg/m3 therefore the king's crown is made up of pure gold.


b.
Density of gold is 2.99x 104 kg/m3 therefore the king's crown is not made up of pure gold.


c.
Density of gold is 2.99x 103 kg/m3 therefore the king's crown is not made up of pure gold.


d.
Density of gold is 4.99x 104 kg/m3 therefore the king's crown is not made up of pure gold.


e.
None of these
