A number of reactions can be used to generate common gases on a laboratory scale. For example, nitrogen can be produced from sodium metal and potassium nitrate as indicated by the balanced equation: 10 Na (s)+ 2KNO3(s)= K2o(S)+5Na2O(s)+N2(g) A common laboratory-scale reaction can also generate oxygen gas by heating potassium chlorate, as indicated by the balanced equation: 2KClO3(s)= 2KCl(s)+3O2(g) What mass of potassium nitrate is needed to generate 161.0 L of gas, composed of 101.0 L of N2 and 60.0 L of O2at 0.920 atm and 285  K, using these two reactions? ? g KNO3

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".
