The mass of sodium carbonate (Na2CO3) is 106 g/mole. The sodium carbonate’s molar mass (Na2CO3) is 106. The molar mass of sodium carbonate (Na2CO3) can be calculated as follows: It has three atoms of oxygen, two atoms of sodium, and one atom of carbon.

Molar Mass of Na2CO3

You can compute the molecular weight as follows:

Na : 2 x 23.0 = 46

C : 1 x 12.0 = 12

O : 3 x 16 = 48

Adding above values i.e, 46 + 12 + 48 = 106

Uses of sodium carbonate:

  • It is a component in the production of paper, soap, and detergents.
  • Additionally used in the production of borax, sodium phosphate, and numerous other sodium compounds. Water glass (sodium silicate).
  • It is utilised in the brick industry as a wetting agent.
  • In toothpaste, it serves as an abrasive and foaming agent.
  • It is utilised to modify pH.
  • It is utilised as a water softener because carbonate precipitates the magnesium and calcium ions in hard water.
  • both as an analytical reagent and as a laboratory reagent for standardizing acids.

Hence, the molar mass of Na2CO3 is 106 g/mole.

The mass of sodium carbonate (Na2CO3) is 106 g/mole. A chemical substance that is inorganic is sodium carbonate. Soda ash is more widely known as sodium carbonate. Trona is used to remove soda ash. Trona is a double salt made of sodium carbonate and sodium hydrogen carbonate that is produced by a number of evaporation processes that occur in lakes.
