Abstract

The article discusses the technique for solving the Stoichiometry to the program 10th grade: derivation of the molecular formula of a substance by mass fractions of elements; derivation of the molecular formula of the substance according to the general formula of the homologous series and density or relative density; derivation of the molecular formula of a substance by weight, volume or quantity of a substance, reagents or reaction products; calculation by chemical equations of the amount of a substance, mass or volume by the amount of a substance, mass or volume a reagent containing a certain proportion of impurities.
