Answer: 0.7g/cm³
Explanation:
Let the average density of Saturn be represented by x.
The average density of earth is 5.5g/cm³ which is 0.1g/cm³ less than 8 times Saturn. This can be formed into an equation as:
8x - 0.1 = 5.5
8x = 5.5 + 0.1
8x = 5.6
x = 5.6/8
x = 0.7
Therefore, the average density of Saturn is 0.7g/cm³
