"On the Molar Mass of Sodium Fluoride"

Research on chemistry, material measurement, molar mass is the key. Today, in the words of sodium fluoride ($NaF $).

Sodium ($Na $) is ranked 11th in the periodic table of elements, and its relative atomic mass is about 23 dollars $. Fluorine ($F $) is in the ninth place, with a relative atomic mass of about 19 dollars $.

Sodium fluoride is composed of a sodium atom and a fluorine atom. Therefore, the molar mass of sodium fluoride is the sum of the relative atomic masses of sodium and fluorine atoms.

That is: $M (NaF) = M (Na) + M (F) $. By substituting the relative atomic masses of sodium and fluorine, we can get $M (NaF) = 23 + 19 = 42g/mol $.

From this point of view, the molar mass of sodium fluoride is $42g/mol $. This value is of great significance in chemical calculation, reaction measurement and many other aspects, and is also a basic constant for chemical study and practice.
