Stoichiometr y Stoichiometry (pronounced stoy-key- OM-uh-tree) is a section of chemistry that involves using relationships between reactants and/or products in a chemical reaction to determine In Greek, stoikhein means element and metron means measure, so stoichiometry literally translated means the measure of elements.  Key Applications of Stoichiometry 1. Production of daily essentials: soap, shampoo, tires, fertilizer, gasoline, deodorant, food products (chocolates, etc.) 2. Environmental monitoring: measuring atmospheric ozone concentration 3. Energy conversion: converting coal into gaseous fuels  For the Reaction Stoichiometry in Solutions, we can perform stoichiometric calculations for aqueous phase reactions just as we can for reactions in solid, liquid, or gas phases. Almost always, we will use the concentrations of the solution as conversion factors in our calculations.  Here are some important terms :to review  Aqueous means dissolved in water, it is written as (aq). The solvent is water. Aqueous solution is a solution in which the solvent is water. Example, a solution of table salt or sodium chloride or known as salt solution.  Solute is the substance that gets dissolved Solution a mixture of solute and solvent (Types: gas solid, liquid-liquid, liquid solid, liquid-gas, solid solid gas). Gas, gas liquid, gas solid, solid – liquid, and solid – gas)  Solvent is the liquid that dissolves solute Concentration means, how much solute is dissolved per volume of solution.  Molarity is the concentration of a substance in solution, expressed as the number moles of solute per liter of solution. Its unit is mol/L and it is indicated by M.  Molality is the concentration of a substance in solution, expressed as the number moles of solute per kilogram of solution. Its unit is mol/kg or molal, indicated as m.  Mole is the SI unit of amount of substance of a specified elementary entity, which may be an atom, molecule, ion, electron, any other particle or a specified group of such particles. Its magnitude is set by fixing the numerical value of the Avogadro constant to be exactly 6.022 x  STEPS IN CALCULATING STOICHIOMETRIC PROBLEMS: STEP 1. Balance the equation. STEP 2. Convert units of a given substance to moles.  STEP 3. Using the mole ratio, calculate the moles of substance yielded by the reaction. STEP 4. Convert moles of wanted substance to desired units. Reminder: There are ways on how to convert the units of substances. Select among the following processes below, as to the required process in the given problem.  1. Mole to mole (mol to mol) 2. Mass to mole (gram to mol) 3. Mole to mass (mol to gram) 4. Mass to mass (gram to gram)  Thanks! CREDITS: This presentation template was created by Slidesgo, and includes icons by Flaticon, and infographics & images by Freepik
