Question

The proprietor of a rock shop insists that a nugget is pure gold. if the nugget occupies a volume of 5.40 ml, what would its mass have to be if it were truly pure gold? (density gold = 19.3 g/ml)

Answer 1

Density of gold = 19.3 g/mL

Density can be calculated from volume and mass of a substance as follows,

`Density = (Mass)/(Volume)`

Given the volume of gold nugget = 5.40 mL

Calculating the mass of gold nugget from density and volume:

`Density = (Mass)/(Volume)`

`Mass = Density * Volume`

`5.40 mL * 19.3 (g)/(mL) =104.22 g`

Therefore, the mass of the nugget is 104.22 g
