Sodium Acetate Formula, Molar Mass, and Uses

# Sodium Acetate Formula, Molar Mass, and Uses

Sodium acetate is a versatile compound that finds its applications in various industries. Its formula, molar mass, and uses make it a key component in many products and processes.

Sodium acetate is represented by the chemical formula CH3COONa. This formula indicates that sodium acetate consists of sodium ions (Na+) and acetate ions (CH3COO-). The presence of the acetate group, composed of two carbon atoms, three hydrogen atoms, and two oxygen atoms, gives sodium acetate its characteristic properties.

## Calculating Sodium Acetate Molar MassÂ

To determine the molar mass of sodium acetate, the atomic masses of its constituent elements need to be considered. The atomic mass of carbon (C) is 12.01 g/mol, the atomic mass of hydrogen (H) is 1.008 g/mol, the atomic mass of oxygen (O) is 16.00 g/mol, and the atomic mass of sodium (Na) is 22.99 g. mass of /mol.

Calculate the molar mass of sodium acetate by adding the atomic masses of each element in the formula.

(2 Ã— C) + (4 Ã— H) + (2 Ã— O) + Na = (2 Ã— 12.01) + (4 Ã— 1.008) + (2 Ã— 16.00) + 22.99 = 82.03 g/mol
