Calculate Neptune's mass given the acceleration due to gravity at the north pole is 11.529 m/s2 and the radius of Neptune at the pole is 24,340 km.

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.
