Acrylic Acid Molar Mass

The acrylic acid molar mass (CH2=CH-COOH) is 72.06 g/mol.

Acrylic acid is a colorless, flammable organic compound with the chemical formula C₃H₄O₂. It is a carboxylic acid with a vinyl group attached to the carboxyl group.

The molar mass of acrylic acid is calculated as follows:

Carbon (C): 3 x 12.01 g/mol = 36.03 g/mol

Hydrogen (H): 4 x 1.008 g/mol = 4.032 g/mol

Oxygen (O): 2 x 16.00 g/mol = 32.00 g/mol

Total acrylic acid molar mass: 36.03 + 4.032 + 32.00 = 72.06 g/mol

Chemical reactions and stoichiometry:
The acrylic acid molar mass is needed to convert between the mass, moles, and number of particles (e.g. molecules, atoms) of acrylic acid in chemical reactions and processes. This allows for accurate quantitative analysis and stoichiometric calculations.

Polymer synthesis and characterization:
Acrylic acid is a monomer used to synthesize polyacrylates and other acrylic polymers. The acrylic acid molar mass is required to determine the degree of polymerization, molecular weight, and other properties of the resulting polymer.

Concentration and solution preparation:
Knowing the molar mass allows you to prepare solutions of acrylic acid at specific molar or mass concentrations, which is important in applications like chemical analysis, material science, and biochemistry.

Thermodynamic and kinetic calculations:
The molar mass is a key parameter needed to calculate thermodynamic properties like molar heat capacity, entropy, and Gibbs free energy. It also factors into reaction kinetics and activation energy calculations.

Identification and purity analysis:
The acrylic acid molar mass can be used as a characteristic property to identify acrylic acid and determine its purity in samples, using techniques like mass spectrometry.
