Step 1:: Identify the molecular formula of acetic anhydride
The molecular formula of acetic anhydride is (C^4H^6O3).
Step 2:: Determine the molar mass of each atom in acetic anhydride
- Molar mass of carbon (C) is 12.01 g/mol. - Molar mass of hydrogen (H) is 1.01 g/mol. - Molar mass of oxygen (O) is 16.00 g/mol.
Step 3:: Calculate the molar mass of acetic anhydride
Molar mass of acetic anhydride = (4 * Molar mass of carbon) + (6 * Molar mass of hydrogen) + (3 * Molar mass of oxygen) Molar mass of acetic anhydride = (4 * 12.01 g/mol) + (6 * 1.01 g/mol) + (3 * 16.00 g/mol)
Step 4:: Calculate the molar mass of acetic anhydride
Molar mass of acetic anhydride = 48.04 g/mol + 6.06 g/mol + 48.00 g/mol Molar mass of acetic anhydride = 102.09 g/mol + 48.00 g/mol
Step 5:: Calculate the molar mass of acetic anhydride
Molar mass of acetic anhydride = 151.19 g/mol (rounded to three decimal places)
Final Answer
The molar mass of acetic anhydride is 151.19 g/mol.
