Question

An archeologist finds a 1.62 kg goblet that she believes to be made of pure gold. She determines that the volume of the goblet is 205 mL. Calculate the density of the goblet. I was wondering if it is 1.62/205? It is saying it it incorrect though!

Answer 1

The answer is

The density (D) is quotient of mass (m) and volume (V):

`D= (m)/(V)`
The unit is g/cm³

It is given:
m = 1.62 kg = 1620 g
V = 205 mL = 205 cm³
D = ?

Thus:

`D= (m)/(V) = (1620g)/(205cm ^(3) ) = 7.90 g/cm ^(3)`

The density of the goblet is 7.90 g/cm³.
