How many conversion factors can be made from a single equality?[Two]2. What do all conversion factors have in common?[The numerator and the denominator have the same value expressed in different units.]3. Why are there not so many mathematical problems in Conceptual Chemistry?[Math is a very powerful tool for gaining a handle on how things work. It's possible, however, for math to get in the way of deeper understanding when the student is not well versed in mathematics. Why? Because more time is thus spent on learning the mathematics than is on learning the concepts that the mathematics are trying to describe. For the benefit of those not so adept at using mathematics, these very concepts are described in Conceptual Chemistry using English. Mathematical problem solving, therefore, is kept to a minimum.]*
