The density of gold is 19.38 g/cm³.
We need to know about the density to solve this problem. Density is a unit that measures how dense an object is. Density can be measured by dividing mass by volume. It can be written as
ρ = m / V
where ρ is density, m is mass and V is volume
From the question above, we know that
m = 15.7 grams
V = 0.81 cm³
By substituting the following parameters, we can calculate the density
ρ = m / V
ρ = 15.7 / 0.81
ρ = 19.38 g/cm³
Hence, the density of gold is 19.38 g/cm³.
