Mastering chemistry is the teaching and learning platform that empowers you to reach every student. Chemical reactions frequently involve both solid substances whose mass can be measured as well as gases for which measuring the volume is more appropriate.
Mass and gaseous volume relationships in chemical reactions the limiting reactant determines the theoretical yield of product. Butane, c4h10, is a component of natural gas that is used as fuel for cigarette lighters. Gas stoichiometryone mole of an ideal gas has a volume. Strategies in chemistry the features of this book 30. Learn chemistry gas stoichiometry with free interactive flashcards. Gas stoichiometry applies when the gases produced are assumed to be ideal, and the temperature, pressure, and volume of the gases are all known. The book guides students through basic chemistry problem solving with. Big idea mass relationships in chemical reactions confirm the law of conservation of mass. With the ideal gas law, we can use the relationship between the amounts of gases in moles and their volumes in liters to calculate the stoichiometry of reactions involving gases, if the pressure and temperature are known. If a andor b are solids or liquids, you use the mass and molar mass to get moles. Relating the idealgas equation and the gas laws 394.
