Answer :
Final answer:
To determine the number of copper atoms in the statue, we use moles concept and Avogadro's number for the calculations.
Explanation:
To determine the number of copper atoms in the statue, we need to use the concept of moles. First, we can calculate the number of moles of copper using the molar mass of copper, which is 63.55 g/mol. Since the mass is given in kilograms, we need to convert it to grams by multiplying by 1000. Then, we can use Avogadro's number, which is 6.022 x 10^23 atoms/mol, to find the number of atoms in the statue. We multiply the number of moles by Avogadro's number to get the answer. Let's do the calculations:
Mass of the copper statue: 137 kg x 1000 g/kg = 137,000 g
Number of moles of copper: 137,000 g / 63.55 g/mol = 2153.69 mol
Number of copper atoms: 2153.69 mol x 6.022 x 10^23 atoms/mol = 1.296 x 10^27 atoms
