On the Molar Mass of Diethyl Malonate Diethyl Malonate is an important compound in organic chemistry. The study of its molar mass is of great significance in many fields of chemistry.

The chemical formula of diethyl malonate is $C_7H_ {12} O_4 $. To obtain its molar mass, it is necessary to calculate the relative atomic mass of each atom. The relative atomic mass of carbon ($C $) is about 12, hydrogen ($H $) is about 1, and oxygen ($O $) is about 16.

In the molecule of diethyl malonate, it contains 7 carbon atoms, so the total relative atomic mass of carbon element is 7 dollars × 12 = 84 $; containing 12 hydrogen atoms, the total relative atomic mass of hydrogen element is 12 dollars × 1 = 12 $; containing 4 oxygen atoms, the total relative atomic mass of oxygen element is 4 dollars × 16 = 64 $.

Adding the sum of the relative atomic masses of each element, the molar mass of diethyl malonate can be obtained as 84 dollars + 12 + 64 = 160g/mol $. This value accurately reflects the molecular mass characteristics of the compound and provides key data support for organic synthesis and reaction mechanism research. In organic synthesis experiments, the amount of reactants can be accurately measured according to their molar mass, and the reaction process and product purity can be controlled. In theoretical research, molar mass data also help to deeply analyze the relationship between molecular structure and chemical properties.
