Answer: The mass of the gold nugget is 386 g.

Step-by-step explanation:

It is known that density of a substance is its mass divided by its volume.

Mathematically, Density =
(mass)/(volume)

It is given that volume is 20
cm^(3) and density is 19.3
g/cm^(3) . Therefore, calculate mass of given gold nugget as follows.

Density =
(mass)/(volume)

19.3
g/cm^(3) =
(mass)/(20 cm^(3))

mass = 386 g

Thus, we can conclude that the mass of the gold nugget is 386 g.

Answer:

The mass of gold nugget, m = 386 grams

Step-by-step explanation:

It is given that,

Volume of gold nugget,
$V=20\ cm^3$

Density of gold nugget,
$d=19.3\ g/cm^3$

We need to find the mass of the gold nugget. Mass per unit volume is called the density of gold nugget. It is given by :

d=(m)/(V)

m=d* V

$m=19.3\ g/cm^3* 20\ cm^3$

m = 386 grams.

So, the mass of the gold nugget is 386 grams. Hence, this is the required solution.
