This worksheet features eleven different dimensional analysis problems. Students utilize molar mass, Avogadro’s number, Molarity and/or mole to mole conversion factor to solve the problems. In the eleven problems, students will:
· Convert grams to moles of a substance and vice versa
· Convert compounds to moles of a substance and vice versa
· Convert mass to atoms or compounds of a substance and vice versa
· Determine the Molarity of a solution with a known number of moles and volume and vice versa
· Determine the volume of water needed to prepare a targeted concentration with a known mass
· Determine the moles of a reactant needed to form a product with a given mass
I provided a complete key with the answers in bold red font that map out and show the work for each problem. I also rounded each answer in the key to honor the multiplication and division rule of significant figures. I included a text box in the upper right corner of the student sheet that profiles how to use each conversion factor.
I assign this activity in my eighth-grade physical science class. A high school chemistry teacher could also utilize this worksheet for an introductory unit about dimensional analysis.
This activity complements the following dimensional analysis worksheets in my store:
