Calculating the Molar Mass of NaC2H3O2

The molar mass of a compound is the sum of the atomic masses of all the atoms in its chemical formula. To calculate the molar mass of NaC2H3O2, we need to know the atomic masses of sodium (Na), carbon ©, hydrogen (H), and oxygen (O). The atomic masses are approximately:

Sodium (Na): 22.99 g/mol
Carbon ©: 12.01 g/mol
Hydrogen (H): 1.01 g/mol
Oxygen (O): 16.00 g/mol

Using these values, we can calculate the molar mass of NaC2H3O2 as follows:

Molar mass of NaC2H3O2 = (1 × 22.99) + (2 × 12.01) + (3 × 1.01) + (2 × 16.00)

Molar mass of NaC2H3O2 = 22.99 + 24.02 + 3.03 + 32.00

Molar mass of NaC2H3O2 = 82.04 g/mol

Importance of Molar Mass in Chemistry

The molar mass of a compound is a fundamental concept in chemistry. It is essential for various calculations, including:

Determining the amount of substance in moles
