"On the Molar Mass of Lead (II) Acetate"

Lead (II) acetate is a common compound in the field of chemistry. To clarify its molar mass, it is necessary to analyze its chemical composition in detail.

The chemical formula of lead (II) acetate is $Pb (CH_3COO) _2 $. The relative atomic mass of lead ($Pb $) is about 207.2, the relative atomic mass of carbon ($C $) is about 12.01, the relative atomic mass of hydrogen ($H $) is about 1.01, and the relative atomic mass of oxygen ($O $) is about 16.00.

In $Pb (CH_3COO) _2 $, there is 1 lead atom, and its mass contribution is 207.2. Contains 4 carbon atoms, the total mass of carbon atoms is 4 dollars\ times12.01 = 48.04 $. Contains 6 hydrogen atoms, the total mass of hydrogen atoms is 6 dollars\ times1.01 = 6.06 $. Contains 4 oxygen atoms, the total mass of oxygen atoms is 4 dollars\ times16.00 = 64.00 $.

Then the molar mass of lead (II) acetate is the sum of the contributions of the atomic masses, that is, 207.2 dollars + 48.04 + 6.06 + 64.00 = 325.3 $g/mol. From this, the molar mass value of lead (II) acetate can be determined, which is of great significance in many fields of chemistry, such as chemical analysis, chemical reaction measurement, etc.
