The relative molecular mass of sodium carbonate is 106.

I. Calculation

Relative molecular mass is the sum of the product of the atomic mass of each atom and the number of atoms in a compound. The relative molecular mass of sodium carbonate (Na2CO3) is the relative atomic mass of sodium (22.99) multiplied by 2, plus the relative atomic mass of carbon (C) (12.01) and the relative atomic mass of oxygen (O) (16.00) multiplied by 3, respectively.

Get the formula: 22.99×2 + 12.01×1 + 16.00×3 = 106. Therefore, the relative molecular mass of sodium carbonate is 106. The relative molecular mass of sodium carbonate is 106.

Two, what is sodium carbonate

1. Sodium carbonate, also known as soda ash or soda, is a common inorganic salt. It is widely used in industry and at home, such as in the production of detergents, glassware, soap and textiles. In chemistry experiments, sodium carbonate is also an important reagent used to neutralize acids and precipitate metal ions.

2, the physical properties of sodium carbonate include white solid, soluble in water, but insoluble in organic solvents. It is relatively stable chemically and is not susceptible to oxidation or reduction reactions. However, when it reacts with acids, carbon dioxide gas is released.

3. Sodium carbonate also plays an important role in human metabolism. Although the body cannot directly absorb pure sodium carbonate, some foods and medicines containing sodium carbonate are used as a source of supplemental sodium and chloride ions. These are essential for maintaining the body's electrolyte balance and normal physiologic function.

Four Differences Between Sodium Carbonate and Sodium Bicarbonate

1, Different Appearance

Sodium Carbonate is a white powder, odorless, while Sodium Bicarbonate is in the form of white crystals or a fine powder, with a slightly salty taste.

2, the stability of different

Sodium carbonate heated to 851 ° C melting does not decompose, strong stability, heat is not easy to decompose. Sodium bicarbonate heated to 270 ° C began to lose carbon dioxide, heat easily decomposed to generate sodium carbonate, water and carbon dioxide gas.

3, different solubility

Sodium carbonate is soluble in water and glycerol, slightly soluble in ethanol, insoluble in propanol. And sodium bicarbonate is soluble in water, slightly soluble in ethanol, insoluble in propanol.

4, different uses

Sodium carbonate is an important chemical raw material and food additives, mainly used in glass, soap, textiles, food and other industries. And sodium bicarbonate is an important bulking agent and neutralizer, mainly used in cookies, bread, steamed bread and other foods.
