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,

$Density = \frac{Mass}{Volume}$

Given the volume of gold nugget = 5.40 mL

Calculating the mass of gold nugget from density and volume:

$Density = \frac{Mass}{Volume}$

$Mass = Density * Volume$

$5.40 mL * 19.3 \frac{g}{mL} =104.22 g$

Therefore, the mass of the nugget is 104.22 g
