[Free Registration/Login may be required to access all resource tools.] In the following online tutorial students will identify three methods for measuring the amount of matter in a sample. They will define the mole and its relationship...

Resource provides notes on Moles and Stoichiometry. Deals with all book-keeping aspects, including as section on yields and limiting reactants. Includes lesson plans, lecture slides and notes, links to related websites, and frequently...

Learn about the chemistry of moles through this slideshow.

Deepen your understanding of the mole in chemistry. Find out the origin of the term, and the formulas it represents.

Students explore the concept of the mole as a measure of quantity. They build spreadsheets that allow them to convert between moles, grams, and atomic mass units for given quantities of everyday items, elements, and simple chemical...

An explanation the mole (named for molecule) and Avogadro's Number. One mole of a substance is equal to 6.022 times 10 to 23rd power units of that substance (such as atoms, molecules, or ions). The number 6.022 time 10 to 23rd power is...

This activity is intended to help students gain an understanding of the mole concept. By determining the molar mass of the element at each station, students will be able to identify the element. Students will learn that the molar mass of...

This activity is designed to assess the comprehension of concepts related to moles.

Using the example of a cake recipe, students find the ratios between different ingredients, which introduces the concept of mole ratios. They then calculate the mole ratios in a chemical equation, and learn how this applies to...

Molarity and osmolarity are two distinct concepts. Molarity (M) is the number of moles of solute per liter of solution. The unit of molarity is the mole (mol). Osmolarity (Osm/L) is the total concentration of all solutes in the solution....

Part of a slide show from Frostburg State University showing the concept of experimental yield. Gives reasons for two yields.
