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

is it 58.0 g/mol?

No. I assume you don't have a clue how to determine the molar mass of a chemical compound. Acetic acids formula, given in the problem, is HC2H3O2. The atomic masses are GIVEN in the problem.
H = ? You have 4 of them so 4 x ..... = .....
C = ? You have 2 of them so 2 x ....... = .......
O = ? you have 2 of them so 2 x ..... = .......
molar mass = total H + total C + total O = grand total. That is the molar mass in g/mol. Post your work in your answer.
