Going through how mistakes in mole conversions typically stem from a poor concept of molar mass. Molar mass is presented in units of g/mol which are better thought of by comparing a single amount of chemical in both grams and moles as well as specifying per as per 1. Mole conversions can be done using dimensional analysis but are better understood when multiplying or dividing by the molar mass even though both methods are similar mathematically. Developing your understanding by looking at which answer is more reasonable helps conceptually and better prepares for stoichiometry.
