The following is an ancient essay written with "NaF Molecular Mass" (molecular weight of sodium fluoride) as the core:

"On the Quality of Things"

Everything in the world contains its essence. Today there is a thing whose composition is combined with sodium (Na) and fluorine (F). Sodium is strong and active; fluoride is also strong. The combination of the two is called sodium fluoride.

If you want to know the molecular weight of sodium fluoride, you should deduce it by scientific method. The atomic weight of sodium has been determined after research, and the same is true for fluorine. The sum of the atomic weights of the two is the molecular weight of sodium fluoride. This value is not random, but is accurately obtained after the study and calculation of many sages.

In the field of chemistry, the molecular weight of all substances is related to their properties and uses. The molecular weight of sodium fluoride is essential in industrial manufacturing and academic research. Knowing its molecular weight is the cornerstone of all practices.

Therefore, studying the molecular weight of sodium fluoride in detail is the key to the nature of exploration and the use of materials.
