Molarity Calculations - Questions

The Molarity Calculations Concept Builder is comprised of 56 questions. The questions are organized into 16 different Question Groups and spread across three different activities. Questions in the same group are rather similar to one another; they may include the same type of given information but be arranged in a different order. The Concept Builder is coded to select at random a question from each group until a student is successful with that group of questions.

There are three activities that can be engaged in through the Concept Builder. Those three activities are differentiated as follows:
 

• Case Studies: Question Groups 1-6 ... Given information about two solutions, identify which has the greatest molarity and by what factor.
• Solution ID: Question Groups 7-12 ... Given information about three solutions, identify any that have a specified molarity
• Solve It!: Question Groups 13-16 ... Given the mass of solute and volume of solution, calculate moles of solute and the molarity of the solution.

The questions from each group are shown below. Teachers are encouraged to view the questions in order to judge which activities are most appropriate for their classes. We recommend providing students two or more options. 

The Physics Classroom grants teachers and other users the right to print these questions for private use. Users are also granted the right to copy the text and modify it for their own use. However, this document should not be uploaded to other servers for distribution to and/or display by others. The Physics Classroom website should remain the only website or server from which the document is distributed or displayed. We also provide a PDF that teachers can use under the same conditions. We have included a link to the PDF near the bottom of this page.
