The mass of an object does not change between Earth and Jupiter; it is a property of the object itself. The weight of an object on Earth (21 N) can be used to calculate its mass using the formula $mass = \frac{weight}{g}$, where $g$ is the acceleration due to gravity on Earth (approximately $9.8 m/s^2$). Thus, $mass = \frac{21 N}{9.8 m/s^2} = 2.1 kg$.
