Density of gold = 19.3 g/mL
Density can be calculated from volume and mass of a substance as follows,
[tex]Density = \frac{Mass}{Volume}[/tex]
Given the volume of gold nugget = 5.40 mL
Calculating the mass of gold nugget from density and volume:
[tex]Density = \frac{Mass}{Volume}[/tex]
[tex]Mass = Density * Volume[/tex]
[tex]5.40 mL * 19.3 \frac{g}{mL} =104.22 g[/tex]
Therefore, the mass of the nugget is 104.22 g
