Stoichiometry

• “stoikhein” meaning element
• “metron” meaning measure
• Stoichiometry. Is the discipline of using mole ratios to calculate relative quantities of reactants and products in reactions
• Mole Ratio. Are the conversion factors between products and reactants based on the coefficient in balanced equation
• Mole. Measuring quantities of very small entities such as atoms, molecules, or other particles. Mole of any atom has a mass in grams equal to the atomic weight of the element
• Molecule. It is a combination of two or more atoms that are held together by a covalent bond. Molecules may contain two atoms of the same element
• Mole-Mole. If the number of moles of one substance is given in the problem, you can determine the number of moles of any other substances in the reaction by using a mole conversion based on the coefficient in the balanced equation
• Stoichiometry. From a balanced chemical equation, you can describe a chemical reaction in terms of quantities of products and reactants.
• Stoichiometry. Derived from two Greek words Stoicheion meaning “Element” and Metron meaning “Measure”
• Mole. It is the measuring quantities of very small entities such as atoms, molecules, or other specified particles.
• Molecule. It is a group of two or more atoms held together by attractive forces known as chemical bonds.
