Diazot oxide ("laughing gas"), which has a slightly narcotic effect, was discovered by the English chemist Humphry Davy in the early 19th century. To obtain N2O, Davy used the thermal decomposition of ammonium nitrate. Calculate the practical yield of diazot oxide if the mass of ammonium nitrate was 11.5 g, and the volume of the obtained N2O was 2.1 L (STP)

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".
