$P b$

Step 1

To find the mass of $1$ mole of $P b$ look up the atomic mass of each element and multiply it by the number of atoms contained in each element in the molecule.

mass of $1$ mole of $P b$ $=$ $(mass of Pb)$

Step 2

Fill in the atomic masses from the periodic table.

mass of $1$ mole of $P b$ $=$ $(207.19999694)$

Step 3

Remove parentheses.

mass of $1$ mole of $P b = 207.19999694 g$
