To find the mass of 0.12 moles of lead (Pb), we need to use the molar mass of lead. The molar mass of lead is approximately 207.2 g/mol.
We can use the formula:
\[
\text{Mass (g)} = \text{Number of moles} \times \text{Molar mass (g/mol)}
\]
Substituting in the values:
\[
\text{Mass} = 0.12 \, \text{mol} \times 207.2 \, \text{g/mol}
\]
Calculating this:
\[
\text{Mass} = 0.12 \times 207.2 = 24.864 \, \text{g}
\]
Thus, the mass of 0.12 moles of lead is approximately **24.86 grams**.
We can use the formula:
\[
\text{Mass (g)} = \text{Number of moles} \times \text{Molar mass (g/mol)}
\]
Substituting in the values:
\[
\text{Mass} = 0.12 \, \text{mol} \times 207.2 \, \text{g/mol}
\]
Calculating this:
\[
\text{Mass} = 0.12 \times 207.2 = 24.864 \, \text{g}
\]
Thus, the mass of 0.12 moles of lead is approximately **24.86 grams**.
