Saturn has about 95 times the mass of the Earth. Would you expect the force of gravity on Saturn to be greater or less than on Earth? Why?

One would experience almost exactly the same gravity as you feel on Earth.

Explanation:

The gravity (I understand on the surface of planet) depends not only the mass of the planet, but also its radius.

It is directly proportional to the mass of the planet and inversely proportional to the square of the radius.

While mass of Saturn is #95# times the mass of the Earth,its radius is #9.5# times that of Earth.

Hence, gravity is #95/9.5^2=1.053# times that of the Earth

and one would experience almost exactly the same gravity as you feel on Earth.
