"Mass" ~=10-11*g

Explanation:

"Density, "rho = "Mass"/"Volume".

Thus "Mass"=rhoxx"volume"

= 19.3*g*cancel(cm^-3)xx0.56*cancel(cm^3) ~=10-11*g.

This calculation is consistent dimensionally. I wanted a mass of gold, and the units cancelled to give an answer in grams, i.e. units of mass, which is a good check that I have multiplied correctly; it's all too easy to make a mistake.

Gold is worth approx $42.38*USD*g^-1. How much is your nugget worth?
