Bright blue slides with bold text and graphics keep the attention of your junior chemists as you impart this information. Through this PowerPoint you will teach what molarity is and how to calculate for a given volume. Practice problems are provided along the way, making this an excellent teaching tool for this topic.
Students determine the molar volume of hydrogen gas. In this molar volume lesson plan, students find the molar volume of hydrogen produced in a reaction between magnesium and hydrochloric acid. They use a eudiometer to measure the volume of the gas and they compare their results to the same gas measured by water displacement. Students calculate their results and answer 4 conclusion questions the lab.
For this molarity lab worksheet, students write down the process they took to determine the molarity of a given sample of a solution of salt. They also make two particular molar solutions in the lab and show their calculations. They answer
Students 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. Students calculate the volume of the gas collected.
In this molarity worksheet, students are given the equation to find moles per liter of solution. They solve ten problems finding molarity of solutions, moles needed to make particular molar solutions and mass needed to make particular molar solutions.
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 enjoy this different approach to chemistry calculations.
In this molarity worksheet, 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 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, density, molar mass and volume of gases.
Students investigate the concept of molarity and its relationship to the concentration of a solution. After mixing chemical solutions, they calculate how many moles of acid and base should be in each solution. They record their results and discuss with the class.
Students are introduced to the concepts of molarity and titration. As a class, they develop a list of the correct steps they need to follow to create a specific concentration of a solution. They design and complete an experiment in which they test their hypothesis about molarity.
Students apply the ideal gas law and Dalton's Law of Partial Pressure to develop an experiment which determine the molar mass of butane from disposable lighters. In small groups, they develop a procedure and have it approved before performing the experiment.
In this molarity worksheet, students solve eleven problems. They determine the concentrations of solutions given moles and volume and mass and volume. They also describe how to determine molarity of a solution given a flask and they sketch a flask and explain how to make a particular molar solution.
In this molarity worksheet, students are given balanced equations and they are to calculate the mass or volume of reactants and products. Students calculate the theoretical, percentage, and actual yield for chemical equations. This worksheet has 7 problems to solve.
In this molarity worksheet, students determine the mass needed to make the given solutions and calculate molarity and volume of solutions. This worksheet has 14 problems to solve.
Your class isn't just going to discuss the digestive system; they're going to act it out! It sounds gross, but it's actually a great idea, it will really help kids visualize the digestive process. First, they discuss and read about the digestive system, then they are assigned parts to play. They use spray bottles for saliva, their hands as crushing molars, and trash bags to eliminate the waste material. I'd say this is a play I'd save for back to school night!
Students conduct an experiment in which they react sodium bicarbonate with hydrochloric acid to determine the molar ration between the two reactants. Students must write correct formula and a balanced chemical equation and explain how it relates to their hypothesis.
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 teacher notes give tips for mentoring minors through the lessons. Suggestions are made for options, community connections, and more. This is a comprehensive resource complete with lab sheets.
The questions ask for one variable to be provided in a set of details about the concentration or molarity of a solution. All calculations for these 15 equations should be shown in order to demonstrate understanding of the work.
Starting with information about molar enthalpy changes and measurement, this instructional activity gives examples and has eight questions about particular substances and state changes.
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 both graphically and with chemical equations. Together, they make a nice, neat presentation that you can use to prepare beginning chemists to start learning about stoichiometry.
