The density of gold is 19.3 g/ml.
Elmhurst College has an interesting exercise the point of which is to demonstrate how the movies skew our perceptions by using the example of a gold bar and how effortlessly they are tossed around in movies causing many to believe that gold is not heavy. The students are asked to calculate the weight of the bar using the dimensions of the gold bars held in the Federal Reserve Bank, which are 7 x 3.625 x 1.75 inches. The calculations conclude that the weight of each gold bar is actually 30.94 pounds! That’s like attempting to carry nearly four gallons of milk at the same time.
Gold Weighs more than Iron!
Did you know that gold weights more than iron? That’s because a bar of gold has more protons and neutrons in every atom causing it to weight more. In fact, gold weighs almost four times that of iron.
