If a 12 pound ball is dropped and attains a velocity of 8.8 ft/s 3.0 seconds whats is the mass of the ball "note the gravity is different then earths and its not given"

Since the ball attains 8.8 ft/s in 3.0 seconds, the gravity of the planet must be:
g_planet = (8.8 ft/s)/(3.0s)
Next, use the equation:
Weight = mass × g_planet.
They give you the weight, and you just calculated g_planet. Solve for mass.

Mass never changes no matter where the ball is. The ball will always accelerate at the same speed as the gravitational constant(ignoring air resistance). Anyways if the given 12 pounds is weight, you must find the gravitational constant, and divide 12 by it.
