Answer:
The mass of Neptune is 
kilograms.
Explanation:
From Newton's Law of Gravitation, the gravitational acceleration of Neptune is determined by the following formula:
(1)
Where:
- Gravitational constant, measured in cubic meters per kilogram-square second.
- Mass of the planet, measured in kilograms.
- Radius of the planet, measured in meters.
- Gravitational acceleration, measured in meters per square second.
If we know that 
, 
and 
, then the mass of Neptune is:
The mass of Neptune is kilograms.
