Sodium carbonate facts

Sodium carbonate is a white, odorless powder that forms a moderately basic solution in water.
It is used mainly in glassmaking, as well as in detergents, water softening, and paper production.
Most of the world's supply comes either from the mineral trona or from the Solvay process, which uses salt, limestone, and ammonia.

FAQ

What is the molar mass of Na2CO3?

The molar mass of sodium carbonate (Na2CO3) is 105.988 g/mol.

How do you calculate the molar mass of Na2CO3?

Multiply the atomic mass of each element by the number of its atoms in Na2CO3, then add the results: 2 × 22.99 (Na) + 1 × 12.011 (C) + 3 × 15.999 (O) = 105.988 g/mol.

What percentage of Na2CO3 is Oxygen?

Oxygen makes up 45.29% of the mass of sodium carbonate (Na2CO3).
