What is the molar mass of acetic acid (CH3COOH)?

Calculate the total mass contributed by each element by multiplying the number of atoms by their atomic masses: For carbon, multiply 2 by 12.01 g/mol; for hydrogen, multiply 4 by 1.008 g/mol; for oxygen, multiply 2 by 16.00 g/mol.

Add all these contributions together to find the molar mass of acetic acid: \(\text{Molar mass} = (2 \times 12.01) + (4 \times 1.008) + (2 \times 16.00)\) g/mol.
