Would a solid have a mass of 180 g on the moon? would it have the same weight on earth as the moon? explain the answer

No, because the Earth is more massive than the Moon, Earth has more gravity. Gravitational pull effects the weight of the object. The Moon's gravity is 1/6x (one-sixth) the gravity of earth. So, an object on Earth will have 1/6x the weight if it was on the Moon.

Example: An object on Earth weighing 60 pounds will weigh 10 pounds on the Moon. [60lbs. / 6 = 10lbs.]
