How many `g` atoms and number of atoms are there in (a) `60 g` carbon, (b) `22.4 g Cu`, an (c ) `72.52 g` lead. Given atomic masses of `C, Cu` and `Pb` are 12,63.6, and 207.2, respectively. (Avogadro's number `= 6.02 xx 10^(23))`.

Explanation

To solve the problem, we will calculate the number of gram atoms (moles) and the number of atoms for each of the given substances: carbon, copper, and lead. We will use the formula for moles, which is:

\[ \text{Moles} = \frac{\text{Given mass (g)}}{\text{Molar mass (g/mol)}} \]

And we will use Avogadro's number to convert moles to the number of atoms:
