1. Find the Molar Mass of Lead

* The molar mass of lead (Pb) is approximately 207.2 g/mol. This means that one mole of lead weighs 207.2 grams.

2. Use the Formula

* Mass = (Number of moles) x (Molar mass)

3. Calculate

* Mass = (0.65 moles) x (207.2 g/mol)

* Mass ≈ 134.68 grams

Therefore, 0.65 moles of lead is approximately 134.68 grams.
