Answer:
The only relationship is that the larger the mass of an object the more gravitational force it has. So... something that has more mass has more gravity. The mass of 4.2kg of gold when transferred to this new planet is still 4.2kg. However, the WEIGHT (not mass) is now doubled to 8.4kg. Mass is constant it is how much matter something is made up of. Weight depends on the gravitational force. Moreover, I would look at other answers too (I'm not entirely confident of saying that the weight is 8.4kg since I don't have any gravitational equations in front of me it just sounds logical).
