Question

The statue of liberty is made of 2 * 10^5 lbs of copper sheats bolted to the framework.How many atoms of copper are on the statue

Answer 1

$200000 \times 454$ is the Answer

Explanation:

To get the number of moles we need to do 2 things:

1) Look up the atomic mass of copper on a periodic table of elements.  This will tell about how many grams of copper atoms exist in a mole.  (63.54 $\frac {grams}{mole}$)

2) Divide the number of grams from above by the grams per mole from the periodic table.  That gives the desired Number of Moles.

Answer becomes $200000 \times 454$ = 90800000 Atoms
