Answer:
The answer to your question is 5.5 x 10¹² kg/km³
Step-by-step explanation:
Data
density = rho = X
mass = 5.94 x 10²⁴ kg
volume = 1.08 x 10¹² km³
Process
To solve this problem use the density formula and simplify it to find the result.
Formula
density =

Substitution
density =

Simplification and result
density = 5.5 x 10¹² kg/km³
