N2  - Inthis study, it was aimed to explore all level university chemistry students,from freshmen to the students who graduated from the university chemistrydepartments, how students define the concepts of density, concentration, andsolvation which are the fundamental and basic concepts of chemistry.Qualitative data were gathered in a test composed of 3 open-ended questionsdistributed to 135 university students comprising two different academicinstitutions: Education faculty and science and art faculty. Students wereasked to provide a written description of three concepts. The data wereanalyzed by using both content analysis method and a concept-evaluation scheme.It was found that students had different understanding levels concerning threeconcepts and problems to the description of them. To add, students had theproblem concerning the concept of mass which is a pre-requisite concept fordensity. The reason for the students’ difficulties with density andconcentration can be related to nature of these concepts that involveproportional reasoning.
