A block is on a ship. Its weight is 45 N. The gravity acceleration g = 10 N/kg. When the block is brought to a space station surrounding the Earth, how much is its mass?

4.5 kg

Explanation:

Since weight, W = mg where m = mass and g = gravity acceleration = 10 N/kg and W = 45 N

m = W/g

= 45 N/10 N/kg

= 4.5 kg

The mass of the block on the ship is thus 4.5 kg. Since mass is an intrinsic property of a substance and does not change with location, the mass of the block when it is brought to as space station surrounding the earth is also 4.5 kg.
