A prospector panning for gold (Au) in a river collects 15.00 g of pure gold. How many Au atoms are in this quantity of gold?

There are 4.59*10^-24 atoms in 15.00 of pure gold.

Explanation:

Molar mass of gold is 196.996g/mol

0.076*(6.022*10^-23)=4.59*10^-24

120,630,890

step-by-step explanation:

110+10=120,620+10=630,880+10=890

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²
