Chemistry: Calculating Molar Mass of Sodium Acetate

What is the molar mass of sodium acetate, NaC2H3O2? The molar mass of sodium acetate, NaC2H3O2, is 82 g/mol.

Understanding Molar Mass Calculation

Calculating the molar mass of a compound involves adding up the atomic masses of each element present in the compound. In the case of sodium acetate, NaC2H3O2, we have sodium (Na), carbon (C), hydrogen (H), and oxygen (O) atoms.

Here are the atomic masses of each element:

Na (Sodium) = 23 g/mol

C (Carbon) = 12 g/mol

H (Hydrogen) = 1 g/mol

O (Oxygen) = 16 g/mol

By multiplying the number of atoms of each element by their respective atomic masses and summing them up, we can find the molar mass of sodium acetate, NaC2H3O2:

Molar mass of NaC2H3O2 = (1 * 23) + (2 * 12) + (3 * 1) + (2 * 16) = 82 g/mol

Therefore, the molar mass of sodium acetate, NaC2H3O2, is 82 g/mol. This calculation helps in determining the amount of a substance needed in chemical reactions, as it provides a way to convert between the mass of a substance and the number of atoms or molecules.
