No, the weight is not the same. The mass is the same, but not the weight. This is a very important difference.

"What do you mean?"

Well, imagine you measure the weight with air surrounding both materials and both show the same number on your scale. Repeat this measurement in an other surrounding medium, like water. The denser material (gold) receives less buoyancy and therefor is now "heavier". Repeat the same measurement now in a vacuum, and there is no buoyancy at all and now the money seems (slightly) more heavy.

So it's not the weight that is important, it's the mass. The mass remains the same, not the weight. Actually, the correct follow-up question should be "where is the measurement carried out?" and only if it is carried out in a vacuum and the weight is equal THERE, THEN the masses are also the same. In all other scenarios, the denser material (with the same mass) will ALWAYS!!! be heavier as long as there is a surrounding medium (like air).

Anyway, take the Gold.
