Answer: There are
moles of Pb are contained in
atoms Pb.
Explanation:
According to the mole concept, 1 mole of every substance contains
atoms.
Hence, number of moles present in
atoms of Pb are as follows.
![No. of moles = \frac{2.49 \times 10^{25}}{6.023 \times 10^{23}}\\= 4.13 \times 10^{-3} mol](https://tex.z-dn.net/?f=No.%20of%20moles%20%3D%20%5Cfrac%7B2.49%20%5Ctimes%2010%5E%7B25%7D%7D%7B6.023%20%5Ctimes%2010%5E%7B23%7D%7D%5C%5C%3D%204.13%20%5Ctimes%2010%5E%7B-3%7D%20mol)
Thus, we can conclude that there are
moles of Pb are contained in
atoms Pb.
