Molarity Ranking Tasks - Questions

The Molarity Ranking Tasks Concept Builder is comprised of 36 questions. The questions are organized into 12 different Question Groups and spread across three different difficulty levels. 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 difficulty levels that can be engaged in through the Concept Builder. Those three levels are differentiated as follows:
 
  • Apprentice Difficulty Level: Question Groups 1-4 ... Each question provides the number of moles of solute and the volume of three different solutions. Students must rank the solutions according to their molarity.
  • Master Difficulty Level: Question Groups 5-8 ... Each question provides the mass of three different solutes, the identity of the solute, and the volume of the solution. Students must rank the solutions according to their molarity.
  • Wizard Difficulty Level: Question Groups 9-12 ... Each question provides the amount (grams or number of moles) of three different solutes, the identity of the solute, and the volume of the solution. Students must rank the solutions according to their molarity.

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.
