Boyant force is equal to the weight of water displaced. Forces on the block of iron are the normal force, the boyant force, and gravity. So determine the net force on the block, then, from the acceleration of gravity, determine the weight.

the mass will be the same if in the same gravity field. Just because it's underwater doesn't change the mass. Now, if the question also asks about density then the iron will sink and the water will just stay there not rising nor sinking (providing the container is of the same density as the water)

The buoyant force on an object submerged in water (or any other liguid) is equal to the weight of the liquid it displaces. Thus, underwater, 7869 kg of iron displaces 1000 kg of water and its weight is 6860 kg.
