Title: Chemsitry help please; converting atoms to grams!
Post by: Boobers87 on Jul 19, 2015
I tried to impress my friend by telling her I bought a new ring that had 2 million (or 2.00 x 106) atoms of elemental gold in it! However, she has mad science skills and saw through the ruse. She quickly pointed out that this only equaled how many grams?



  A.1.19 × 1032 
  B.6.54 x 10-16 
  C.8.43 × 10-21 
  D.1.97 x 108

Divide by 6.022x10^23, then multiply by 79.
