Only three slides comprise this collection. The first defines molecular weight and molar mass. The second lists the molar mass and number of particles in a mole of several substances. The third is a chart depicting a chemical reaction...

High schoolers determine the molar mass of a gas. In this molar mass of a gas lesson plan, students use the vapor density of an organic solvent to determine its molar mass. They vaporize the solvent and collect the vapor. Once it is...

Acids and bases have a love-hate relationship. They balance each other so nicely, but they are complete opposites! Learners use these concepts and titration to calculate the molar mass of an unknown substance. The experiment...

Let the data tell the story. A lab activity has pupils collect temperature data on solutes as they melt and freeze. They use their data to create a cooling curve and then calculate the molar mass using the freezing point depression.

In this moles worksheet, students define a mole and convert grams to moles or moles to molecules. Students convert specific mass of compounds to moles. This worksheet has 1 true or false, 6 short answer, 3 fill in the blank, and 15...

Ready to teach your class about molar mass and solution concentration? Make time for an interactive resource that will challenge their reasoning and problem-solving skills. Science scholars calculate the molarity of several solutions...

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...

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...

For this mass worksheet, students determine the number of moles from a given molar mass and volume being sure that they use the correct conversion factors. This worksheet has 12 problems to solve.

For this ideal gas law, molar mass and density worksheet, students read about how the molar mass and density of a gas can be determined from the ideal gas law. They solve five problems using the ideal gas law to find the pressure,...

In this molecules, moles and molar masses worksheet, students find the atomic masses of 8 elements, they write the formulas for 6 diagrams of molecules and they find the molecular masses of 12 compounds. Students also find the fraction...

High schoolers find the standard molar volume of a gas. In this molar volume of a gas lesson plan, students react magnesium metal and hydrochloric acid and collect the hydrogen gas produced using a gas collection tube. High schoolers...

Chemistry pros calculate mass, volume, concentration, or molarity of five different solutions. This tidy worksheet makes an appropriate homework assignment when studying molarity.

Francis Raoult discovered the change in boiling points of solutions varies by the number of particles in the solution. Scholars apply the concept to determine the molality of a solution based on the change in boiling point. They use an...

In this molarity instructional activity, students determine the concentration or molarity for each of the solutions. Students manipulate the molarity formula to calculate the moles, mass, or volume of each problem.

In this chemistry overview worksheet, students calculated the volume of different gases and liquids given in a word problem. Students had to calculate the molecular mass and write the empirical formula and the molecular formula.

What better way is there to introduce conservation of mass than a few simple experiments? Young chemists conduct two chemical reactions, take the masses of reactants and products, then compare their results to determine...

Wow! This is one of the most exhaustive presentations on finding chemical formulas that you will come across! Beginning with the basics, and leaving junior chemists with procedures and concrete examples, this PowerPoint certainly...

In this measuring chemicals worksheet, students determine the accuracy and precision of measurements and distinguish between the two. They find the percent composition of compounds, the molar mass of compounds and the volume of gases at...
