Acetic acid, with the chemical formula CH3COOH, is a carboxylic acid that consists of two carbon atoms and a –COOH group. To determine the molar mass of acetic acid, we need to sum the atomic masses of all the elements present in the compound. The molar mass of a substance is the mass of one mole of that substance, and it is expressed in grams per mole. One mole of a substance contains a large number of atoms or molecules, and the total mass of all these atoms or molecules is referred to as the molar mass.
For acetic acid, the molar mass is calculated by adding the atomic masses of the constituent elements. The carbon atom has a molar mass of 12.01 g/mol, the hydrogen atom has a molar mass of 1.008 g/mol, and the oxygen atom has a molar mass of 16.00 g/mol. By summing the atomic masses of the elements present in acetic acid, we can determine its molar mass.
Calculation of Molar Mass
The molar mass of acetic acid (CH3COOH) is calculated as follows:
Molar mass of CH3COOH = (2 × 12.01) + (4 × 1.008) + (2 × 16.00) g/mol
Molar mass of CH3COOH = 24.02 + 4.03 + 32.00 = 60.05 g/mol
Understanding the Calculation
The molar mass of acetic acid is 60.05 g/mol. This value is obtained by adding the molar masses of carbon, hydrogen, and oxygen in the compound, weighted according to their respective frequencies in the chemical formula.
By calculating the molar mass of acetic acid, we can understand the mass of one mole of this compound and use this information for various chemical and analytical purposes.
