Abstract: A proposal is made to conduct discussions and carry out simple mathematical tasks in the chemistry laboratory targeting the understanding of the magnitude of various constants and/or quantities which are described and frequently used by first year undergraduate students. Examples are presented about the numeric and/or descriptive procedures utilized to clarify the meaning of expressions and the actual “size” of quantities which are involved in a number of chemical laboratory applications, within the framework of an introductory general chemistry class.
Keywords: chemical principles, university students, magnitudes, values of observables
