General chemistry class members engage in a mini-unit on mole conversions. Through nine lab activites with varying degrees of difficulty, they practice measuring mass and volume, molar calculations, and stoichiometry. Terrific...

As to be expected from the American Chemical Society Olympiad Examinations Task Force, this 60-question test tops the charts in terms of excellence. It consists entirely of multiple choice questions designed to assess a year's worth of...

Here is a general chemistry worksheet that incorporates practical applications. Four questions employ critical thinking about solutions, boiling and freezing points, and molar mass. Your class will practice what they learn in class by...

Here is a straightforward practice test for first year chemistry learners. Responders balance equations, identify types of reactions, represent electron configurations, and solve stoichiometry problems. Keep this handy to use as...

A full-fledged practice final prepares pupils for their general chemistry final exam. If they complete these 57 multiple-choice questions correctly, they will be well-prepared. Note: even though the questions are multiple-choice, there...

All units and significant figures should be used correctly as part of this check on molar mass calculations.  These word problems range in complexity and present the missing variable in different ways. Your young scientists might...

To provide practice in balancing chemical equations, you can give your class this worksheet. It is straightforward, easy to read, and thoroughly tests for understanding of this vital skill in general chemistry. Those who complete this...

This compact collection of slides explains the history and use of the mole unit. Relative atomic mass, as John Dalton understood it, is explained. Avogadro's number is also introduced. The mole, or the unit for the amount of a substance,...

Prepare your chemistry charges for stoichiometry with this PowerPoint. The objective is to be able to calculate molar mass for different compounds. Beginning with the foundational definition of moles and moving through atomic and...

In preparation for an introduction to chemistry exam, play Chemistry Jeopardy with your class. The categories include molar relationships, phases of matter, atomic structure, chemical nomenclature, and scientific investigation. If the...

Gases, volume, mass, and density are the main topics combined in these calculations. Each of the 14 questions gives a situation with certain amounts of substance at a particular temperature and pressure and asks for one of the other...

In this thermochemistry worksheet, students indicate whether the given processes are endothermic or exothermic reactions. Kids complete the phase change diagram as well as define a given set of vocabulary words. Students calculate mass...

In this moles worksheet, students practice calculating the number of moles based on grams of a compound. Students use the rate of reaction equation to determine the rates of specific reactions. This worksheet has 10 problems to solve.

In this chemistry worksheet, students calculate to find the molar mass of water. Then they identify how many moles of hydrogen atoms and oxygen atoms they would have in a beaker. Students also write the chemical formula of cholesterol.

In this molecules worksheet, students calculate the mass or volume of a certain number of moles of a compound. There are 3 difficulty levels of this worksheet, each one has 6 problems to solve.
