Abstract: 
This work is an extension of the two previous studies which aims at verifying the
importance of the cognitive variables to problem solving in Chemistry across topics and levels. The
previous studies show that the five cognitive variables namely, Specific Knowledge, Non-Specific but
Relevant Knowledge, Concept Relatedness, Idea Association and Problem Translating Skill, are the
important predictors of problem-solving performance in the topic of Grade 12 Electrochemistry. This
present study involved 115 Grade 9 Chemistry students, aged between 13 and 16, solving Mole
Concept problems with the familiarity levels ranging from familiar to partially familiar. Four of the
five cognitive variables, Specific Knowledge, Concept Relatedness, Idea Association and Problem
Translating Skill, have been found to be significant in predicting problem-solving performance with
Idea Association being the most significant. The study also suggests that the difference in the topics
and levels appeared to have little effect on the importance of these variables on problem-solving
performance.
