The mass is an intrinsic property of a substance which means that wherever it is placed, the mass would stay the same. This being said, the mass of the container of rocks in the Earth's surface is still 65 kg.
To determine the weight of the object on the Earth's surface, we multiply the mass with the acceleration due to gravity, 9.8 m/s².
Weight = mg
Substituting with the known values,
Weight = (65 kg)(9.8 m/s²)
Weight = 637 N
Answer: 637 N
