Final answer:
The mass of acetic acid can be calculated using the molar mass of acetic acid and water.
Step-by-step explanation:
The mass of acetic acid can be determined using the formula:
Mass of acetic acid = Molar mass of acetic acid - Molar mass of water
In this case, the molar mass of acetic acid is given as 60.06 g/mol and the molar mass of water is 18.02 g/mol. Therefore, the correct equation to find the mass of acetic acid is (#2 - #3).
