APFIVE Calculating Moles From Mass
All of the following statements about converting grams to moles are true except:
A
To convert grams to moles, one must multiply the mass in grams by the molar mass.
B
The formula $$\text{moles} = \text{mass (g)}/\text{molar mass (g/mol)}$$ correctly relates the mass of a substance to the number of moles.
C
Dividing the given mass in grams by the atomic weight (molar mass in g/mol) yields the number of moles.
D
Unit consistency is crucial; the molar mass must be expressed in grams per mole for the conversion to be valid.
