Molarity Calculations
The Molarity Calculations Concept Builder focuses learner attention upon the dissociation of ionic compounds in water. There are three scaffolded activities. The first activity -
Case Studies - presents learners with information about two aqueous solutions - the amount of solute and the volume of water. Students must identify which solution has the greatest molarity and the factor by which it is greatest. The second activity -
Solution ID - presents learners with information about three aqueous solutions and challenges them to identify any which have a specified molarity. The third and final activity -
Solution ID - challenges learners to calculate the molarity of a solution if given the solute identity (formula), the solute mass, and the volume of the water in milliliters. There are a total of 56 questions in this Concept Builder. They are organized into 18 different Question Groups and spread across the three activities. Question-specific help is provided for each of the 18 situations. The built-in score-keeping makes this Concept Builder a perfect candidate for a classroom activity.
Users are encouraged to open the Concept Builder and explore. There is no need for an activity sheet for this Concept Builder. However, the 18 different groups of questions can be printed. View
