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?
Yo just tell us the answer bro
i think it's probably 60.0 g/mol lol
To determine the molar mass of acetic acid (HC2H3O2), you need to calculate the sum of the atomic masses of all the atoms in the chemical formula.
The atomic mass of hydrogen (H) is 1.008 amu, carbon (C) is 12.011 amu, and oxygen (O) is 15.999 amu.
In acetic acid, there are two hydrogen atoms, two carbon atoms, and two oxygen atoms.
Calculating the molar mass:
(2 * H) + (2 * C) + (2 * O) = (2 * 1.008) + (2 * 12.011) + (2 * 15.999) = 2.016 + 24.022 + 31.998 = 58.036 amu
Therefore, the molar mass of acetic acid (HC2H3O2) is approximately 58.0 g/mol.
So, yes, your initial guess of 58.0 g/mol is correct.
30 g/mol?
no
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.
