For example, a problem might provide the equation 2 A + 3 B → 3 C and ask, "given 25 grams of B and unlimited amount of A, how much C will be produced?" This is called a mass-mass problem. The most common stoichiometric problem will present you with a certain amount of a reactant and then ask how much of a product can be formed. It is a very mathematical part of chemistry. Stoichiometry deals with calculations about the masses (sometimes volumes) of reactants and products involved in a chemical reaction. ![]() The Merriam-Webster dictionary defines stoichiometry as "a branch of chemistry that deals with the application of the laws of definite proportions and of the conservation of mass and energy to chemical activity". Rows are called periods, and display properties known as periodicity. The elements are arranged so they are in columns with similar chemical properties. They are numerically ordered by their atomic number, which is the number of protons in the nucleus of an atom. The periodic table of the elements organizes the known elements by properties.
