what is the molar mass of acetic acid (hc2h3o2)?

(note: h = 1.008 amu, c = 12.011 amu, o = 15.999 amu)

120.1 g/mol
30.0 g/mol
58.0 g/mol
60.0 g/mol

Molar mass of acetic acid is 60 g/mol

Explanation:

Look at the formula:

CH₃COOH

We have:

Let's sum the mass of each element

24 g/mol + 4 g/mol + 32 g/mol = 60 g/mol

the ratio of the conjugate base to the acid required to attain the desired ph.
