Module 4 Intro

Module 4—Properties of Solutions

Lesson Summary

In this lesson you explored the following essential question:

• How can the concentration of solute in a solution be expressed?

You have performed calculations to express the concentration of various solutions as % V/V, % W/V, % W/W, and parts per million. Each means to express concentration has a purpose and a practicality about it. In the next lesson you will learn about another way to express concentration—one that has greatest use in the laboratory when chemical reactions are studied.

Lesson Glossary

concentration: a property of solutions; the mass, volume, or number of moles of solute present in proportion to the quantity of solvent or total solution
