1. Identify the Elements and Their Atomic Masses
* Lead (Pb): 207.2 g/mol
* Carbon (C): 12.01 g/mol
* Hydrogen (H): 1.01 g/mol
* Oxygen (O): 16.00 g/mol
2. Count the Number of Atoms of Each Element
* Lead (Pb): 1
* Carbon (C): 2 x 2 = 4
* Hydrogen (H): 3 x 2 = 6
* Oxygen (O): 2 x 2 + 2 = 6
3. Calculate the Total Mass
* Pb: 1 x 207.2 g/mol = 207.2 g/mol
* C: 4 x 12.01 g/mol = 48.04 g/mol
* H: 6 x 1.01 g/mol = 6.06 g/mol
* O: 6 x 16.00 g/mol = 96.00 g/mol
4. Add Up the Individual Masses
207.2 g/mol + 48.04 g/mol + 6.06 g/mol + 96.00 g/mol = 357.3 g/mol
Therefore, the molar mass of lead acetate, Pb(CH₃COO)₂, is 357.3 g/mol.
