The Moon takes just as long to rotate around its own axis as it does to revolve around the planet (Earth). How many other moons in the Solar System share this feature?

none

most of them
If the rotational frequency of a satellite is larger than orbital frequency, a small torque counteracting the rotation arises, eventually locking the frequencies in a tidal lock. Pluto and Charon are the extreme example, being locked to each other.
