How heavy is gold?

Question

1 square inch.

Answer 1

Weight is a function of the gravitational force being applied to it at any give time. You are looking for mass.

2 dimensions is not enough to calculate a mass. Maybe its 1 square inch by microns thick or maybe its 1 square inch and a foot thick.

The density of gold is 19.3  g/cc.

Density = mass x volume

Find your volume (3 dimensions) and you can find your mass.

Answer 2

It is  2 and half times heavier than iron.
