#20.1# #kg#
weight of #197# #N#

Explanation:

This question requires you to use Avogadro's number to convert the atoms to moles, and then use the molar mass of gold (#197g#/#"mol"#) to convert moles to grams.

I'm assuming by "how heavy" you mean mass, but if you wanted to calculate weight you would need to calculate a force by using #F=ma# where #F# is the force is the weight in Newton, #m# is the mass, and #a# is the acceleration is gravity at Earth's surface (#9.8m#/#s^2#)
