Interpretation:
The pathway for solving a “grams of A” to “grams of B” by the use of conversion factor has to be chosen from the given options.
Concept Introduction:
Using the
Molar mass of a substance gives a relationship between the number of grams and number of moles of that particular substance.
The Chemical formula subscript also provides relationship between the number of moles of substance to the number of moles of its individual components present in the substance.
All the three above relationship can be put into a single diagram as shown below,
