The discussion centers on calculating the number of moles from the gram formula weight of sodium cyanide (NaCN). The correct interpretation is that 0.01 gram formula weight of NaCN directly equates to 0.01 moles, as 1 gram formula weight corresponds to 1 mole of the substance. The confusion arises from the misconception that gram formula weight should be divided by the molar mass (49 g/mol for NaCN) to find moles, which is incorrect in this context. The term "gram formula weight" is clarified as synonymous with "mole" for this calculation.
