How much fuel is in a fuel tank of a rocket ship?

The amount of fuel in a rocket ship's fuel tank varies significantly depending on the type and size of the rocket. For example, the SpaceX Falcon 9 rocket carries about 1,000,000 pounds of propellant, while the Saturn V, used during the Apollo missions, held approximately 12 million pounds of fuel. The specific fuel capacity is designed based on the mission requirements, payload, and intended orbit.
