Answer:
19.3 g/cm³
Explanation:
From the question given above, the following data were obtained:
Mass of nugget of gold = 965 g
Volume of nugget of gold = 50 cm³
Density =?
The density of a substance is simply defined as the mass of the substance per unit volume of the substance. Mathematically, it is expressed as:
Density = mass / volume
With the above formula, we can obtain the density of the nugget of gold as illustrated below:
Mass of nugget of gold = 965 g
Volume of nugget of gold = 50 cm³
Density of nugget of gold =?
Density = mass / volume
Density of nugget of gold = 965 / 50
Density of nugget of gold = 19.3 g/cm³
Thus, the density of the nugget of gold is 19.3 g/cm³.
