Calculate the number of atoms of copper represented by 127.08 g of copper. 1. 1.20 × 1024 atoms 2. 2.00 atoms 3. 1.30 × 1024 atoms 4. 2.16 atoms

Answer : The number of atoms of copper are

Explanation :

First we have to calculate the moles of copper.

Mass of Cu = 127.08 g

Molar mass of Cu = 63.5 g/mole

Now we have to calculate the number of atoms of copper.

As we know that, 1 mole of substance contains number of atoms.

As, 1 mole of copper contains number of copper atoms.

So, 2.00 mole of copper contains number of copper atoms.

Therefore, the number of atoms of copper are
