The Correct Answer and Explanation is :

To find the molar mass of aluminum acetate, we first need to determine its correct chemical formula. Aluminum acetate is formed by the reaction of aluminum hydroxide (Al(OH)₃) and acetic acid (CH₃COOH). The reaction can be described as:

[ \text{Al(OH)}_3 + 3 \text{CH}_3\text{COOH} \rightarrow \text{Al(CH}_3\text{COO)}_3 + 3 \text{H}_2\text{O} ]

The chemical formula for aluminum acetate is ( \text{Al(CH}_3\text{COO)}_3 ).

To calculate the molar mass, we sum the atomic masses of all the atoms in the formula:

  • Aluminum (Al): ( 26.98 \, \text{g/mol} )
  • Carbon (C) in acetate (three acetate ions, each with two carbon atoms): ( 3 \times 2 \times 12.01 \, \text{g/mol} = 72.06 \, \text{g/mol} )
  • Hydrogen (H) in acetate (three acetate ions, each with three hydrogen atoms): ( 3 \times 3 \times 1.008 \, \text{g/mol} = 9.072 \, \text{g/mol} )
  • Oxygen (O) in acetate (three acetate ions, each with two oxygen atoms): ( 3 \times 2 \times 16.00 \, \text{g/mol} = 96.00 \, \text{g/mol} )

Adding these together, the molar mass of aluminum acetate, ( \text{Al(CH}_3\text{COO)}_3 ), is calculated as follows:

[ 26.98 \, \text{g/mol} + 72.06 \, \text{g/mol} + 9.072 \, \text{g/mol} + 96.00 \, \text{g/mol} = 204.112 \, \text{g/mol} ]

Therefore, the molar mass of aluminum acetate is approximately 204.112 g/mol.

This calculation illustrates the importance of understanding the structure and stoichiometry of a compound to accurately determine its molar mass. Knowing the molar mass is essential for preparing solutions with precise concentrations and for carrying out various chemical reactions where the stoichiometry must be carefully controlled. It also aids in the empirical determination of a compound’s formula based on its percent composition, which is crucial in many analytical techniques in chemistry.
