The road map in the text shows that to convert from one unit to another, you must use the as an intermediate step. conversion factor(s) is/are required to convert mass to moles. conversion factor(s) is/are required to convert the number of molecules of a compound to the mass of that number of molecules.

Conversion factor;

Molar mass;

Avogadro's constant and molar mass

Explanation:

Firstly, an intermediate step is to define the conversion factor that will be then used in a conversion technique called dimensional analysis in order to convert from one unit to another. An example of a conversion factor would be, for example, 1 L = 1000 mL, which can be manipulated as a fraction, either or ;Secondly, in order to convert mass to moles, we need to know the molar mass of a compound which has a units of g/mol (that is, it shows how many grams we have per 1 mole of substance.Thirdly, Avogadro's constant, tells us that there is number of molecules or atoms in 1 mole of substance. We need two conversion factors to convert the number of molecules to a mass: firstly, we need to convert the number of molecules into the number of moles using Avogadro's constant and then we need to use the molar mass to convert the moles obtained into mass.
